Question

A car starts from Hither, goes 50 km in a straight line to Yon, immediately turns around, andreturns to Hither. The time for this round trip is 2 hours. The average speed of the car forthis round trip is:

Answer 1

Answer:

average speed = 50 km/hour

Explanation:

we have formula of average speed = distance travelled / time taken

here total distance is 50 + 50 = 100 km

and total time taken is 2 hours

that is average speed is 100/2  = 50 km/hour

if it ask for average velocity than ans would be zero because average velocity  =  displacement / time

and here displacement is 50 - 50 = 0km
