A car travels at 40 km/h for 30 min and 60 km/h for 15 min.How far does it travel in this time? Here’s the best way to solve it. A car travels along a straight line for first half time with speed 40 km/h and second half time with speed 60 km/h . the mean speed of the car is ? Q. a car has to cover the distance of 60 km/hr.if half of the total time it travels with speed 80 km/hr and rest in half time its speed becomes 40 km/hr the avg speed of the car is 5.The speedometer readings of a car are shown below. Find the acceleration of the car and its displacement. Time Speedometer 9:25 am 36 km/h 9:45 am | 72 km/h A car moves with a speed of 40 km per hour for 15 minutes and then with a speed of 60 km per hour for the next 15 minute calculate the total distance - 7169412 krishnanhoneydew krishnanhoneydew 18.12.2018 Speed = 40 km/hr. Required time = 5 hour. Concept Used: Distance covered = Speed × Time. Calculation: The car covered total distance = 40 × 5 = 200 km. The car will cover the same distance in 8 hours. Required speed = 200/8 km/hr. ⇒ 25 km/hr. ∴ The speed of the car should be 25 km/hr. A car for half of its time at 80 km/hr and for rest half of time at 40 km/hr. Total distance covered is 60 km/hr. What is the average speed of car ? A car travels 300 kilometers in 6 hours. Select a car to see more technical specs and information including top speed, power, torque and more. Car 0-100 mph (0-160 kph) List - Figures and Specs Between 4 and 5 seconds. Tayyab April 14, 2017, 3:56pm 7. This issue has nothing to do with humming sound or high RPMs, my car shakes at the speed of 20 to 40 KM/H only, regardless of any RPM or shift number or road condition and yes I’ve auto trans. My car usually shifts at 2000 to 2500 RPMs and if I accelerate more it shifts at 3000 to 3500 RPMs or as according to Routine Car Maintenance: 60,000–100,000 miles. Hopefully, by the time you hit the six-figure range, the car has been paid off and you’re able to invest even more in its upkeep. Keep in mind that the better you maintain the vehicle, the more you’ll be able to get for it when it’s time to trade it in or sell it. 75,000 miles How many km/h in 1 m/s? The answer is 3.6. We assume you are converting between kilometre/hour and metre/second. You can view more details on each measurement unit: km/h or m/s The SI derived unit for speed is the meter/second. 1 km/h is equal to 0.27777777777778 meter/second. Note that rounding errors may occur, so always check the results. In Scientific Notation. 25 miles per hour. = 2.5 x 10 1 miles per hour. = 4.02336 x 10 1 kilometers per hour. A car moving with a speed of 40 k m / h r can be stopped by applying breaks for 2 km. If the same car is moving with a speed of 80 k m / h r, what is the minimum stopping distance? Assume constant retardation. 8 K m; 2 K m; 4 K m; 6 K m Suppose they meet when A travelled x km. So, B would have travelled 280 − x km We know that T i m e = D i s t a n c e S p e e d When the cars meet, they would have travelled at the same time. So, x 30 = 280 − x 40 On cross multiplying and simplifying, we get x = 120 So, Time taken by A to meet = 120 30 = 4 hours As they left at 3 pm, they Maintenance of engine of new cars after 3,000 - 5,000km. Usually we will maintain the car periodically after every 3000 km - 5000 km or 3-6 months of use. However, experts still recommend maintenance of newly purchased vehicles at about 3,000 km or 3-4 months for domestic use. Thus the car engine will be best taken care of in the first One family leaves 20 minutes ahead of the other family and travels at an average speed of 40 kilometers per hour. What would the speed of the second family's car need to be if the family is to reach the camp at the same time as the first family? -----1st family DATA: Rate = 40kph ; distance = 280 km ; time = d/r = 7 hrs----- .
