Question

Nia is training for a marathon. Her average speed during training so far is 5.8 miles per hour. If she runs at that rate for a training run that is 1 hour and 12 minutes long, how far will Nia run?

A. 4.83 miles

B. 6.96 miles

C. 7.25 miles

D. 4.64 miles

Answer 1

To find out how far Nia will run, multiply her average speed of 5.8 mph by the time converted to hours (1.2 hours), which results in a distance of 6.96 miles.

Step-by-step explanation:

The question asks how far Nia will run if she maintains an average speed of 5.8 miles per hour for 1 hour and 12 minutes. To find the distance, we use the formula Distance = Speed × Time. First, we need to convert the time to hours since the speed is in miles per hour. One hour and 12 minutes is the same as 1 + (12/60) hours, which can be simplified to 1.2 hours.

Next, we calculate the distance by multiplying her average speed by the total time in hours:

Distance = 5.8 miles/hour × 1.2 hours = 6.96 miles.

The correct answer is B. 6.96 miles.

Answer 2

Step-by-step explanation:

5.8miles an hour = 5.8/60miles per minute = 0.0967miles per minute.

1hr and 12minutes = 72minutes

The total distance covered = 72 * 0.0967 = 6.9624miles

That's approximately 6.96miles or option B.
