Question

Define average speed. The odometer of a car reads 4500 km at the start of the

journey and 5200 km at the end of the journey. If the time spent for the journey

is 7 hours and 15 minutes, find the average speed of the car in km/h.​

Answer 1

Answer:

AVERAGE SPEED CAN BE DEFINED AS THE TOTAL DISTANCE TRAVELLED IN UNIT TOTAL TIME.

AV. SPEED = TOTAL DISTANCE / TOTAL TIME

INITIAL DISTANCE=4500

FINAL DISTANCE=5200

TOTAL DISTANCE=700 KM=700000m

TOTAL TIME =7*3600 s + 15*60 s =26100 s

AV.SPEED = 700000 m/ 26100 s =26.81 m/s.

IF THE MEANING OF THE QUESTION IS DIFFERENT, THE TOTAL DISTANCE IS 5200 km

or 5200000 m

then 5200000/26100 = 199.23 m/s.

HOPE IT HELPS.
