A swimmers swims across a river 37.0m wide at 1.25m/s and swims back at 2.00m/s. what is the swimmers average speed?
Homework Answers
Time taken by 1st shift
t 1 = 37 / 1.25 = 29.6 sec
Time taken by 2nd shift
t2 = 37 / 2 = 18.5 sec
Av speed
Vs = 37*2 / ( t1 + t2)
Vs = 1.54 m/s

A 70 m wide river flows from north to south at a speed of 3.2 m/s. A swimmer swims relative to the water at a rate of 4.6 m/s aiming across the river at an angle of 24 degrees north of east. What is the speed of the swimmer with respect to the shore? How far downstream (south), from a point directly across the river, does the swimmer hit the shore?

A river has a steady speed of 0.450 m/s. A student swims upstream a distance of 1.70 km and swims back to the starting point. If the student can swim at a speed of 1.40 m/s in still water, how long does the trip take swimming up and down in the current)? If the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.)

An outdoorsman observes a Squirtle swimming in a river, As the Squirtle swims with the river's current, the outdoorsman observes it traveling 220 m in 28.3 s. The Squirtle turns around and swims against the current, taking 45.7 s to travel the same distance of 220 m. Assuming the Squirtle's speed relative to the water and the river's speed relative to the outdoorsman are both constant, what is the Squirtle's swimming speed relative to the water? Squirtle's speed relative to...
