Answer:
11 minutes and 15 seconds (11.25 minutes/ 11 and 1/4)
Step-by-step explanation:
create the corresponding ratio by dividing 200 by 15, 200 calories per 15 minutes. Which equates to 40 calories every three minutes which means 40/3 or 13 1/3 calories every minute. You can verify this by multiplying 15 and 40/3 to get 200 again.
The last step is to divide the calories burned by the corresponding ratio (40/3)
150/(40/3) = 11.25
and .25 or 1/4 of 60 seconds(in a minute) is 15 since 60/4 = 15.
