The answer is 9.75 miles.
To determine the distance Grace ran in 1.5 hours, we can set up a proportion:
Distance ran / Time taken = Total distance / Total time
Let's plug in the given values:
Distance ran / 1.5 hours = 26 miles / 4 hours
Now, we can solve for Distance ran:
Distance ran = (1.5 hours * 26 miles) / 4 hours
Calculating this expression gives us:
Distance ran = 39 / 4
Distance ran = 9.75 miles
Therefore, Grace ran 9.75 miles in 1.5 hours.
To find out how far Grace ran in 1.5 hours, we can use the concept of proportionality. We know that Grace ran a total of 26 miles in 4 hours.
So, we can set up a proportion to find out how far she ran in 1.5 hours:
Distance in 4 hours / Time in 4 hours = Distance in 1.5 hours / Time in 1.5 hours
Let's solve this proportion:
26 miles / 4 hours = x miles / 1.5 hours
Cross-multiplying, we get:
4 hours * x miles = 1.5 hours * 26 miles
4x = 39
Dividing both sides by 4, we find:
x = 9.75 miles
Therefore, Grace ran 9.75 miles in 1.5 hours.
