Question

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 odomete 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.​

Answer 1

Answer:

0.75 km/min and 2700 km/h

Explanation:

Initial reading = 57321 km

Final reading = 57336

So, distance traveled, s = final reading - initial reading = 57336 - 57321 = 15 km

Initial time = 8:30 AM

Final time = 8:50 AM

So, time for which the car traveled, t = 20 min

Now, speed in km/min = s/t = 15/20 = 3/4 = 0.75 km/min

To change it to km/hrs, multiply it by 3600.

So, speed in km/h = 0.75 * 3600 = 3*3600/4 = 3*900 = 2700 km/h
