Matt drove 1.5 miles in 28.2 seconds. kelvin drove 19,800 feet in 71.8 seconds. in miles per hour and to the nearest tenth, how much faster was matt driving compared to kelvin?

So the first thing you want to do is convert Kelvin's total feet to miles: 3.75 miles
Now, see how many 28.2 seconds and 71.8 seconds are in a one hour.
60 times 60= 3600
3600/28.2=127.659574
3600/71.8=50.1392758
Now you want to multiply their times by the total miles they took.
127.659574 times 1.5= 191.5
50.1392758 times 3.75=188
191.5-188=3.5 miles
Tell me if this helps!!

What is the last question i don’t see it?
