To find out how far Grace ran in 1.5 hours, we can use the equation:
Distance = (Time taken / Total time) * Total distance
Distance = (1.5 hours / 4 hours) * 26 miles
Distance = (3/8) * 26 miles
Distance = 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 26 miles in 4 hours.
To calculate the distance she ran in 1 hour, we divide the total distance by the total time:
26 miles / 4 hours = 6.5 miles per hour
To find the distance she ran in 1.5 hours, we multiply the distance per hour by the number of hours:
6.5 miles per hour * 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 a simple proportion. We know that Grace ran a total of 26 miles in 4 hours.
First, we can calculate Grace's average speed by dividing the total distance she ran by the total time it took her:
Average speed = 26 miles / 4 hours = 6.5 miles/hour
Now, we can use this average speed to find how far Grace ran in 1.5 hours. We set up a proportion:
miles in 4 hours / 4 = miles in 1.5 hours / 1.5
Simplifying the proportion gives us:
26 / 4 = x / 1.5
To solve for x, the distance Grace ran in 1.5 hours, we can cross-multiply:
4 * x = 26 * 1.5
x = (26 * 1.5) / 4
Solving this equation, we find that x ≈ 9.75 miles.
So, Grace ran approximately 9.75 miles in 1.5 hours. The correct answer is 9.75 miles.
