Problem #8: Strength and Conditioning Coach
Your athlete can swim at an average rate (speed) of v metres per second in still water. She has two races
coming up: one in a lake with no current and the other in a river with a current of 0.5 m/s. Each race is
800 m, but in the river race she swims the first half of the race against the current and the second half
distance
with the current. Note: you may find the equation speed =
useful for this problem!
time
a) Determine an expression for the time it takes her to complete the lake swim.
b) Determine a simplified expression for the time it takes her to complete the river swim.
