So if there’s 64 tables and you want them to be arranged in a square then 8 tables would be in each row! I got that because the square root of 64 is 8. Another way to think of it is 8^2 = 64

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 a
Savatey [412]

Answer:

7.5 miles per hour.

Step-by-step 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\times 5\times 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}=\frac{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.
