Chapter 4, Problem 29A

Calculate the distance (in km) that Charlie runs if he maintains an average speed of 8 km/h for 1 hour.

To determine

The distance run by person C for a given average speed and time of travel.

Answer to Problem 29A

The distance travelled by person C is $8\text{}\text{km}$

Explanation of Solution

Given:

Person C runs a particular distance with a constant speed of 8 km/hr for 1 hour.

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 of Charlie is 8 km/hr and time is 1 hour. Thus, the distance travelled is given by,

  $\begin{array}{c}\text{Distance =8×1}\\ =8\text{ km}\end{array}$

Conclusion:

The distance travelled for the given average speed and time is 8 km.
