Answer:
2:40 PM
Step-by-step explanation:
Terry's 5-minute head start has reduced the distance between them by ...
(5 min)(50 m/min) = 250 m
After Tao starts, at 2:05 PM, the remaining 2350 -250 = 2100 m of distance is being closed at the rate of 50 +10 = 60 m/min. It will take ...
(2100 m)/(60 m/min) = 35 min
to close the remaining distance between the rowers. 35 minutes after Tao starts is 2:05 + 0:35 = 2:40 PM.
