Question

A treadmill counts 1/5 mile as one lap. the display of the treadmill indicates the number of laps already completed and highlights how much of the current lap has been completed. create a display that shows a total of 13/10 miles run

Answer 1

6.5laps

Explanation:

If one lap=1/5mile

How many laps will equate to 13/10miles.

Essentially the question tests for cross-multiply to simplify the equation and therefore determine the value of the missing variable.

`(1)/(5)mile=1 \ lap\\(13)/(10)miles=x \ laps?\\x \ laps=\frac{{(13)/(10)*1}}{(1)/(5)}\\x=6.5 \ laps`

The dispaly for 13/10 miles is displayed as 6.5
