The velocity graph of a car accelerating from rest to a speed of 120 km/h over a period of 30 seconds is shown. Use the Midpoint Rule with n = 6 to estimate the distance (in km) traveled during this period.
I found the midpoints and estimated the points, getting
(2.5,30),(7.5,65),(12.5,90),(17.5,105),(22.5,115), and(27.5,119)
I don't know how to convert from seconds to hours. I know that I can get the answer by multiplying the sum of all the converted y-values by 5, I just need to know how to convert.
Thanks in advance!

There are 60 seconds in a minute and 60 minutes in an hour, so there are 60*60=3600 seconds in an hour. So you can convert from seconds to hours by dividing by 3600.
