Answer: 38
Step-by-step explanation:
Since the new side will be 2 times the length, 2 x 19 = 38.
Total time taken by Sam before Al caught up with him = 15+10 = 25 minutes
In hours = 25 minutes = 25/60 = 5/12 hrs
Distance covered by Sam = Distance covered by Al = Speed (Sam) * time taken = 3.2*5/12 = 4/3 miles.
Al takes 10 minutes to cover that distance. Therefore,
Al's speed = Distance/time = (4/3)/(10/60) = (4/3)*(60/10) = 8 mph
