Question

The odometer of a car reads 800 km at the start of agrip and read 1400 km at the end of the trip .If the trip took 15hr .Calculate average speed of the car

Answer 1

Answer:

40 km/hr

Explanation:

Given:

• Initial reading of the odometer = 800 Kilometres
• Final reading of the odometer = 1400 Kilometres
• Time taken for travelling = 15 hrs

To find:

• Average speed of the car

Average speed = total distance/Total time

Distance covered = Final reading of the odometer - initial reading of the odometer

Distance covered = 1400-800

Distance covered = 600 km

Average speed = 600km/15hrs

Average speed = 40 km/hr

The average speed of the car is equal to 40 km/hr
