Question

the odometer of a car reads 80060 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 80040 km? express the speed in km/h also.

Answer 1

Explanation:

current reading of odometer of a car = 80040 km

current time showing on clock = 8:30am .

odometer reading at 8:50am = 80060km

so distance cover by car in 20 min = 80060km-80040 km

= 20km .

so speed of car = distance ÷ time

= 20 × 1/3

= 6.6 km / h
