So the bottom line is for vehicle weight so if you look at the bar at the top it says 25 so go to the graph and put a dot on 25 and then it says city mp is 27 so you put a dot between 25 and 30 and the connect it with a line
The book has 100+44=144 pages.
She spent 2+1=3 hours on reading = 3*60=180 minutes
The "speed" will be 144/180 = 0.8 pages per minute
Oh, I think the answer I posted was wrong I'm goung to double check.
