The odometer of a car reads 57321.0 km when the clock shows the time 8.30 AM. What is the distance moved by the car if at 8.50 AM, the odometer reading has changed to 57336.0 km ?
Calculate the speed of the car in `km//min` during this time.

Explanation

Initial reading of the odometer of the car = 57321.0 km
Final reading of the odometer of the car = 57336.0 km
Distance covered by the car = Final reading of the odometer of the car - Initial reading of the odometer of the car
= 57336.0 - 57321.0 = 15 km
The given car starts at 8:30 a.m. and stops at 8:50 a.m.
Therefore, time taken by the car to cover the distance is (8:50 - 8:30) min = 20 min
Distance covered by the car = 15 km
Time taken by the car = 20 min
Speed `=("Distance covered")/("Time taken")=(15)/(20)=0.75 ` km/min
