Chapter 4, Problem 30A

Calculate the distance you will travel if you maintain an average speed of 10 m/s for 40 seconds.

To determine

The distance travelled.

Answer to Problem 30A

The distance travelled is $\text{400 m}$

Explanation of Solution

Given:

A particular distance with a constant speed of 10 m/s for 40 s.

Formula used:

The distance travelled by an object moving with an average speed for a given time is expressed as,

  $\text{Distance }=\text{Average speed }\times \text{time }$

Calculation:

Here, the average speed is 10 m/s and time is 40 s. Thus, the distance travelled is given by,

  $\begin{array}{c}\text{Distance }=\text{40×10}\\ =400\text{ m }\end{array}$

Conclusion :

The distance travelled is 400 m.
