Question 414450
You depart at 9 AM
For each hour you hike, you are traveling 1.5 miles.
 For each mile, you are using up 550 calories of energy.
 Write and equation to predict the time at which you will have "burned up" all 
the energy from your 1600-calorie breakfast.
:
Let t = time in hrs to burn 1600 calories
:
We know that the total amt of calories expended will be:
550 * 1.5 * t
: 
Find t when it equals 1600 calories
550 * 1.5 * t = 1600
825t = 1600
t = {{{1600/825}}}
t = 1.9393 hrs, which is 1 + .9393*60 ~ 56 minutes
:
So the time you run out of energy:
9:00 + 1:56 = 10:56. AM
