Question

your drive your car for 4.5 hours at an avarage speed of miles per hour.how far did you go?

Answer 1

Well it depends, let’s say MPH is the variable M, you would take M and multiply it by the amount of hours. Thus an expression would look like this:

M x 4.5

If you were looking for an actual answer other than an expression, then please provide the miles per hour.
