Mathematics

While driving from Orlando, Florida, to Tampa, Florida, a family travels 4 miles in 5 minutes. If they travel at the same rate for the next half hour, approximately how many miles will they travel in that half hour?

A.20 miles
B.24 miles
C.40 miles
D.48 miles

答案和解析

答案：B

解析：

Option B is correct. 30 minutes is six times as long as 5 minutes, so the car will travel six times as far as it traveled in 5 minutes, or 4*6 miles.
