Question

A man walks 10 miles in x hours. How far does he walk in one hour? Which expression represents this? 10 + x miles 10x miles 10/x miles

Answer 1

A man walks 10 miles in x hours

⇒ x hours = 10 miles

Find 1 hour:

x hours = 10 miles

To find 1 hour, we divide both sides by the quantity on the left-hand-side.

Divide both sides by x:

x ÷ x  hour = 10 ÷ x miles

x ÷ x will give us 1:

1  hour = 10/x miles

Answer: 10/x miles

Answer 2

Given A man walks 10 miles = x hours. Now find 1 hour: x hours = 10 miles.

To find 1 hour, need to divide both sides by the quantity.

Divide both sides by x, x ÷ x  hour = 10 ÷ x miles, x ÷ x = 1, so 1 hour = 10/x miles. So the correct answer is C.
