It takes a motor boat 3 hours to make a downstream trip with a current of 7 miles per hour the return trip against the same current took 5 hours find the speed of the boat in still water
Since the distance downstream (with the current) equals the
distance upstream (against the current), and if we: Let B stand for
the speed (rate in mph) of the boat in still water, and using the
formula rate X time = distance, the equation will be: (B+7) x 3 =
(B-7) x 5 3B + 21 = 5B - 35 56 = 2B B = 28 mph
Traveling downstream, the current will cause the boat to go
faster so the 7 mph current is added to the boat's still water
speed. Traveling upsteam the current slows or decreases the boat's
rate so the current's speed is subtracted from the boat's still
water speed.

How far can a plane fly if it flies at a rate of 170 miles per hour for 4 hours with unlimited fuel
4 x 170 miles = 680 miles
A plane traveling at a constant speed is able to travel 600 miles in 5 hours How fast was the plane flying
A plane which has travelled 600 miles in 5 hours was travelling at a speed of 120 miles per hour.
Speed = Distance / Time
Therefore the speed of the plane = 600 / 5 = 120.
120 miles per hour
