Question

8. John is traveling to a meeting that is 28 miles away. He needs to be there in 30 minutes. How fast does he need to go to make it to the meeting on time?

A. 25 mph
B. 37 mph
C. 41 mph
D. 49 mph
E. 56 mph

Answer 1

This can be tricky because of the mixed units (some information is in miles, some in minutes. I'd tackle this first by making sure the units were the same.
Given information: 28 miles need to be traveled, answer choices are in miles, so let's make the time information in miles too: he needs to be there in 30 minutes, which is 0.5 hours
That's the tricky part of this question, making sure the total time is in hours, same as the rate.
Time X Rate = Distance
(0.5 hours) (Rate in mph) = 28 miles
So he the rate he needs is 56 mph. So the answer is "E".

Hope that's helpful!
