Question

A car travels 500 m in 50 s, then 1500 m in 75 s. Calculate its average speed
for the whole journey.

Answer 1

Answer:

First calculate total distance travelled:

500 + 1500 = 2000 m

Then calculate total time taken:

50 + 75 = 125 s

Then use the formula to calculate average speed:

 

Average Speed  = Total Distance/Total Time

average speed = 2000 ÷ 125

average speed = 16 m/s

Calculating distance

The distance travelled by an object moving at an average speed can be calculated using the equation:

distance travelled = average speed X time
