In Routine #1, she does only running, burning 15.5

calories per minute.

In Routine #2, she burns 17

calories walking. She then runs at a rate that burns 11.25

calories per minute.

For what amounts of time spent running will Routine #1 burn at least as many calories as Routine #2?

Use t

for the number of minutes spent running, and solve your inequality for t

.

Answer 1

15.5t ≥ 17 + 11.25t

Can you solve for t and answer?
