A rowing team practices rowing 2 miles upstream and 2 miles downstream.
The team can row downstream 25% faster than they can row upstream.
Let r represent their rate upstream.
Write and simplify an expression for the amount of time they spend rowing.
:
Let r = rowing speed upstream
then
1.25r = rowing speed downstream
:
Write a time equation; time = dist/speed
rowing time = +
simplify
r.t = = =
cancel r
r.t. = , simplified expression for time spent rowing
