Answer: Robert ran faster than Jocab
Step-by-step explanation:
Convert the improper fraction to a proper fraction
Jocab = 5miles in 1 1/2 hours, therefore, 1 1/2 hours = 3/2 hours, to convert to minute will be 3/2 x 60 = 90 minutes
Robert = 3 miles in 3/4 hours = 45 minutes
If Robert runs 3 miles in 45 minutes, by the end of 90minutes, Robert would have covered 6miles, while Jocab covered 5miles in 90 minutes, therefore, Robert ran faster than Jocab.
