Question

A first place finisher in a cross country meet ran 5,000 meters in 871.7 seconds. What was his average speed?​

Answer 1

Answer : His average speed was, 5.735 m/s

Solution : Given,

Total distance covered = 5000 meter

Total time taken = 871.7 seconds

Average speed : It is defined as the total distance covered in total amount of time.

Formula used :

`\text{Average speed}=\frac{\text{Total distance covered}}{\text{Total time taken}}`

Now put all the given values in this formula, we get his average speed.

`\text{Average speed}=(5000m)/(871.7s)=5.735m/s`

Therefore, his average speed was, 5.735 m/s
