Question

The odometer of a car reads 2000 km at the start of a trip and 2400 km at the end of the trip. If the trip take took 8 h, calculate the average speed of the car in km/h and m/s.

Answer 1

Initial reading of distance = 2000km
final reading of distance = 2400km

total distance covered betweeen this period = 400km

time taken = 8h

average velocity = total distance/ total time taken
= 400/8
= 50km/h.

= 13.88 m/s

Therefore the average velocity here would be 50km/h or 13. 88m/s.

Answer 2

Hey!

______________

Initial reading of the odometer = 2000 km
Final reading of the odometer = 2400 km
Time taken = 8h
Total distance travelled = 2400-2000= 400 km

Average speed = Total distance travelled/Total time taken

Avg. speed = 400/8 = 50 km/h
= 13.88 m/s

Thus, average speed of car is 13.88 m/s
