Ishi walked a total of 2 1/2 miles on a treadmill. He walked a constant sate of 4 MI per hours. Which expressions shows how long, in minutes, Ishi walked on the treadmill? ​

Time taken T = 2.5 miles/ 0.067 miles per minute

Step-by-step explanation:

In this question. We are asked to give the expression that shows how long in minutes that should be walked on the treadmill.

Now, let’s look at what we have in the question. We have a distance of 2.5 miles and a speed of 4 mph, read as 4 miles per hour.

The question is a term of how long. This means what we are trying to calculate refers to the time taken to walk a total of 2.5 miles on the treadmill at a speed of 4mph.

Mathematically, we know that the time taken would be equal to the distance walked on the treadmill mill divided by the speed used to walk this distance over the treadmill.

This can be written in the equation form as T = D/S

Now if we look at our speed, it is written in hours, but the question stipulated minutes. So what do we do? We simply make a conversion from 4mph to 4mpm. To do this , we simply divide 4mph by 60 to give 0.067mpm.

We now move on to write the time taken. This would be:

T = 2.5 miles/0.067 miles per minute

this is false ^.^ lol
