How would I create a CONVERSION FACTOR for this? Trying to convert mph TO miles per minute mentally is hurting my brain...
Triathlete Dan runs along a 2-mile stretch of river and then swims back along the same route. If Dan runs at a rate of 10 miles per hour and swims at a rate of 6 miles per hour, what is his average rate for the entire trip in miles per minute?
A) 1/8
B) 2/15
C) 3/15
D) 1/4
E) 3/8
