A family goes on a trip. They drive 65 mph. Write an equation using two variables to show the relationship between the number of hours driven, h , and the total amount of miles drive, m. How far did they drive after 7 hours?

Answer 1

The equation relating the number of hours driven, h, and the total number of miles driven, m, is:

m = 65h

To find out how far they drove after 7 hours, we substitute h = 7 into the equation:

m = 65(7) = 455

After 7 hours of driving at 65 mph, the family drove 455 miles.

Answer 2

What’s the equation for it?

Answer 3

The equation relating the number of hours driven, h, and the total number of miles driven, m, is:

m = 65h
