Question

Her exercise today, Amanda plans to both run and swim. Let

r
be the number of laps she runs and let
s
be the number of laps she swims. Each lap she runs takes her
5
minutes, and each lap she swims takes her
3
minutes.
She wants to exercise for more than
30
minutes today. Using the values and variables given, write an inequality describing this.

Answer 1

r = laps she runs
s = laps she swims
each r (laps she runs) takes 5 min.
each s (laps she swims) takes 3 min.
She wants to run for 30 min.

So your inequality should = 30
