Question

The distance traveled by a race car is 7km in 100sec. What is it's speed?

Answer 1

`\text{ Speed=}0.07\text{ m/s}`

Explanation:

Average speed is the measure of the rate of movement of a body expressed as the distance traveled divided by the time taken:

`\begin{gathered} \text{ Speed=}\frac{dis\tan ce}{\text{time}} \\ \end{gathered}`

Therefore if the car traveled 7 km in 100 sec:

*Remember to convert kilometers to meters:

`\begin{gathered} \text{ Speed=}(7)/(100) \\ \text{ Speed=}0.07\text{ m/s} \end{gathered}`
