Question

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

Answer 1

Gn:d1=2000km
d2=2400km
t=8hrs
average speed=total distance traveled/total time taken
=2000+2400/8
=4400/8
=550km/h

1km=1000m
2000km=2000*1000m=2000000m
2400km=2400*1000m=2400000m
1hr=60secs
8hr=8*60secs=480secs
average speed=total distance traveled/total time taken
=2000000+2400000/480
=4400000/480
=9166.666666m/S

HOPE THIS WILL HELP YOU
