Integration Word Problem
Can someone help me solve problem #24 that I attached. I am a little confused by the wording of part a and b. Would I solve a by taking the interval 04 for my low and from 5 to 1 for my high interval?
Then take 5 to 7 for the low and 8 to 6 for the high of part b?

You've got the idea. Parts (a) and (b) are essentially the same  to get the lower bound, you use the smaller value (so for 01, you use 50, for 12, you use 70, etc.). To get the upper bound, you use the larger value (so for 01, you use 70, for 12, you use 97, etc.). In (a) you sum the 5 intervals from 0 to 5, and in (b) you sum the 8 intervals from 0 to 8.
To do (c), you use your upper and lower bound for how much has leaked from 0 to 8, and calculate how much time it takes to empty the tanker at a constant 720 gal/h in both cases.
