. The odometer of a car reads


57,321.0 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 57,336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also.

 

Best Answer

Ans. when time is 08:30 a.m.: the distance read by Odometer = 5,7321.0 km

When time is 08:50 a.m.: The distance read by Odometer = 57,336.0 km

Distance travelled by car = distance read by odometer at 08:50 am – distance read by Odometer at 08:30 am

= 57,336.0 km-  5,7321.0 km

Distance travelled= 15 km

Time taken = Final time – initial time = 8:50 am – 8:30 am

Time taken t = 20 minutes

Speed of the car= distance/ time taken

= 15km/20 minutes

Converting minutes into hours, divide by 60 as 1 hour = 60 minutes
