Given:

Total Distance traveled = 280 + 280  = 520 miles
(since the boat traveled back and forth)

Total Time = 7 hours + 14 hours = 21 hours

Determine the speed of the boat in still water.

Formula for velocity:

v = d/t

v = velocity

d = distance

t = time

Solution:

Substitute the given values of distance and time to the formula for velocity.

v = d/t

v = 520 miles/ 21 hours

v =24.76 mi/hr

Final answer:

v =24.76 mi/hr
