The odometer of a car reads 57318 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 09:00 AM, the odometer reading has changed to 57338 km? Calculate the speed of the car in km/min, km/h and m/s during this time.​

The initial reading of the odometer of the car =57321.0 km

The final reading of the odometer of the car = 57336.0 km

The car starts at 8:30 AM and stops at 8:50 AM.

Distance covered by car = (57336 - 57321) km = 15 km

Time taken between 08:30 AM to 08:50 AM = 20 minutes = 20/60 hour = 1/3 hour

So Speed in km/min

Speed = (Distance travelled)/ (Time)

= (15km)/ (20min)

= 0.75km/min

Speed in km/h Speed = (Distance travelled)/ (Time)

= (15km)/ (1/3h)

= (15 x 3) km/ (1h)

= 45km/h

Answer 2

Answer:

Distance =57336.0km−57321km=15km

Speed in km/min =15km/20min= 3/4 km/min

Speed in km/hr=

3)km/hr=45km/hr.
