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
