Answer:
After 15 minutes, they are moving apart at 8100 ft/sec
Step-by-step explanation:
Using the direct proportion
For the man, 4ft/sec
4ft -----1 sec
Xft ----- 60 x 15 sec
X = 3600 ft/sec
For the woman, 5ft/sec
5ft -----1 sec
Xft ----- 60 x 15 sec
X = 4500 ft/sec
After 15 minutes they are moving apart at 4500 + 3600 = 8100 ft/sec
