Question

the odometer of the car reads 2000 km in the starting of the trip and 2400 kilometre at the end of the trip .if it took 8hours. calculate the speed in km/h and m/s​

Answer 1

Answer:

total distance traveled=2400-2000=400km

time taken = 8hrs

so, speed = 400/8=50kmph

Answer 2

Answer:

Speed in km/h is 50km/hr

Speed in m/s is 13.88m/s

Explanation:

Reading at starting = 2000km/hr

Reading at end = 2400km/hr

So the distance travelled = 400km/hr

Time for travelling the 400km/hr = 8hrs

Speed = Distance/Time

= 400/8 = 50 km/hr

Speed in m/s = 50km/hr × 5/18 = 13.88m/s
