Question

Grace ran a 26-mile marathon in 4 hours. How far did Grace run in 1.5 hours?
9.75 miles.
4.33 miles.
156 miles
69.33 miles

Answer 1

To find out how far Grace ran in 1.5 hours, we can set up a proportion using the given information.

Let's set up the proportion using the distance and time:

Distance/Time = Distance/Time

We know that the distance Grace ran in 4 hours is 26 miles. Let's replace the distance and time in the proportion:

26 miles/4 hours = x miles/1.5 hours

To find x, we can cross-multiply the proportion:

4 hours * x miles = 26 miles * 1.5 hours

4x = 39 miles-hours

To isolate x, we divide both sides of the equation by 4:

x = 39 miles-hours / 4

Simplifying the expression on the right side, we get:

x = 9.75 miles

Therefore, Grace ran 9.75 miles in 1.5 hours.
