Diane plans to drive 30 miles to her interview. If she averages 25 miles per hour, how long will it take her to get there?
Answers:
(A) 50 minutes
(B) 55 minutes
(C) 1 hour and 12 minutes
(D) 1 hour and 20 minutes
Is it going to take her more or less than an hour?
To find out how long it will take Diane to get to her interview, we need to divide the distance she plans to drive by her average speed.
Diane plans to drive 30 miles, and her average speed is 25 miles per hour.
To get the answer in hours, we can divide 30 miles by 25 miles per hour:
30 miles ÷ 25 miles/hour = 1.2 hours.
Since 1 hour is equal to 60 minutes, we can convert 0.2 hours to minutes by multiplying 0.2 by 60:
0.2 hours × 60 minutes/hour = 12 minutes.
Therefore, it will take Diane 1 hour and 12 minutes to drive 30 miles to her interview.
So, the correct answer is (C) 1 hour and 12 minutes.
