2/3 * 15 miles = 10 miles then time for 10 miles travel is t1 = 10/40 = 1/4 then remaning distance is 5 miles time for 5 miles travel is t2 = 5/60 = 1/12 t1+ t2= 1/3 in seconds * 60 = 20 min

13.5 miles at 18mph from house to school
Well, if Van drove 6 hours at the speed of 54 mph, you would have to multiply 54x6=324. So, your excellent answer would be 324
72 mphHOW FAST IS THE 18-WHEELER GOING?!Well, lets see. Since the rental is slower than the 18-wheeler by 8 mph, we'll add 8 to 72. This gives us 80 mph.so 80 mph is the speed of the 18-wheeler, while the rental is 72 mph.
