Sebastian has to be in Modesto, 66 miles away, by 4pm. He starts driving at 2:48pm. At what average speed (mph) will he need to drive to arrive at exactly 4pm?

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
