2. The velocity graph of a car accelerating from rest to a speed of 60 km/h over a period of 30 seconds is shown. Estimate the distance traveled during this period. (Use M_{6}to get the most precise estimate. Round your answer to two decimal places.)

My work: Deltax = 30-0/6 =5

M6=5(15+33+45+52+57+58) = 1300 which is wrong according to the site

I placed the midpoints in the middle @ 2.5, in the middle of 5 and 10, in the middle of 10 and 15, in the middle of 15 and 20 and in the middle of 20 and 25. The last part of the graph gives a very small portion of the graph that my TA says should be counted so I gave it a value of 58.

Im honestly at a dead end here. Appreciate any help!

Sorry for all of this but I appreciate anyone who can help me. thanks!!
