How long will it take to go 63 miles if you are driving 55 miles an hour?

Answer 1

Method 1:

(55/1) = (63/x)

Solve the equation for x and you got it (x being in hours)!

Method 2:

I took 55 mph and divided it by 60 minutes to find out that you'd be driving about .92 miles per minute. I then took 63 miles and divided that by .92 to come up with the roughly 68.48 minutes it would take you.

This works out to 1 hour 8 minutes and 30 seconds.Approximately.

Method 3:

If you want to be precise (like getting the correct answer on an exam)...

Divide 63 by 55 and get 1.1454545... which is the number of hours.

Multiply the non-integer part of that value (the part to right of the decimal) by 60 and get 60*.1454545 = 8.72727272... which is the minutes.

Again, multiply the non-integer part of that value (the part to right of the decimal) by 60 and get .72727272*60 = 43.63636363... which is the seconds.

That gives you the final result: 1 hour, 8 minutes, and 43.6 seconds, precisely.
