The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 08:50 AM, the odometer reading has changed to 57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also.

Given:
Initial odometer reading = 57321.0 km
Final odometer reading = 57336.0 km

Initial time = 08:30 AM
Final time = 08:50 AM

Distance moved = 57336.0 – 57321.0 = 15.0 km
Time taken = 20 minutes

Speed in km/min = 15.0 ÷ 20 = 0.75 km/min
Speed in km/h = 0.75 × 60 = 45 km/h

Hence distance moved = 15.0 km  &  Speed = 0.75 km/min or 45 km/h
