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
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.
To find out how far Grace ran in 1.5 hours, we can use the proportion:
distance in 1.5 hours / 1.5 hours = distance in 4 hours / 4 hours
Let's solve for the distance in 1.5 hours:
distance in 1.5 hours = (26 miles / 4 hours) * 1.5 hours
distance in 1.5 hours = (6.5 miles/hour) * 1.5 hours
distance in 1.5 hours = 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 formula: distance = speed × time.
First, let's calculate Grace's speed. We know she ran a 26-mile marathon in 4 hours, so her speed is 26 miles / 4 hours = 6.5 miles per hour.
Next, we can substitute the speed and time into the formula:
distance = 6.5 miles/hour × 1.5 hours = 9.75 miles.
Therefore, Grace ran 9.75 miles in 1.5 hours. So the correct answer is 9.75 miles.
