Charlie is choosing between two exercise routines.

In Routine #1, he does only running, burning
18.5
calories per minute.
In Routine #2, he burns
22
calories walking. He then runs at a rate that burns
16.3
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
.

Waking would burn more calories. I think. I may be wrong. Sorry.
