Multiple Choice

A car travels 250 m in 10 s. What is its average speed?

Average speed equals total distance divided by total time. With 250 m travelled in 10 s, the calculation is 250 ÷ 10 = 25 m/s. This matches the given time for the distance. If the speed were 50 m/s it would cover 250 m in 5 s, 20 m/s would take 12.5 s, and 10 m/s would take 25 s, so those speeds don’t fit the 10 s interval.
