Question

Mr.Ward runs a lot. He ran 45 minutes each day, 5 days each week , for 16 weeks . In that time, he ran 450 miles. What was his average rate in miles per hour

Answer 1

7.5 miles per hour.

Explanation:

We have been given that Mr. Ward runs a lot. He ran 45 minutes each day, 5 days each week, for 16 weeks.

First of all, we will find time for that Mr. Ward ran in 16 weeks.

We will multiply 5 by 16 to find number of days for that Mr. Ward ran and then we will multiply the result by 45 minutes to find the time.

`\text{Time for that Mr. Ward ran in 16 weeks}=16* 5* 45\text{ minutes}`

`\text{Time for that Mr. Ward ran in 16 weeks}=3600\text{ minutes}`

Now, we will divide 3600 minutes by 60 minutes to convert time into hours as:

`\text{Hours}=(3600)/(60)=60`

Now, we will divide 450 miles by 60 hours to find Mr. Ward's average speed as:

`\text{Mr. Ward's average speed}=\frac{450\text{ miles}}{\text{60 hours}}`

`\text{Mr. Ward's average speed}=\frac{7.5\text{ miles}}{\text{ Hour}}`

Therefore, Mr. Ward's average speed in 7.5 miles per hour.
