A. 1 hour
B. 1.5 hours
C. 2 hours
D. 2.5 hours

Answer 1

Nora has 6.55 miles left in the race, and at her speed of 8 miles per hour, it will take her a little over 49 minutes to finish. Therefore, the answer is A. 1 hour.

Step-by-step explanation:

First, we need to determine how far Nora has already run. The race is 26.2 miles long and she has completed 3/4 of it. To find out how many miles she has run, we calculate 3/4 of 26.2 miles:

Distance run = 3/4 × 26.2 miles

Distance run = 19.65 miles

This means Nora has 26.2 miles - 19.65 miles = 6.55 miles left to run. Given her speed of 8 miles per hour, we can find out how much time it will take her to finish the remaining distance:

Time = Distance / Speed

Time = 6.55 miles / 8 miles per hour

Time = 0.81875 hours

Since 0.81875 hours is a little over 49 minutes, which is less than an hour, the correct answer is A. 1 hour.
