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 A and the total amount of miles drive. m. How far did they drive after 7 hours?

Answer 1

One possible equation is:

m = 65A

where m represents the total amount of miles driven and A represents the number of hours driven. This equation assumes that the car maintains a constant speed of 65 mph throughout the trip.

To find how far they drove after 7 hours, we can substitute A = 7 in the equation:

m = 65(7) = 455

Therefore, they drove 455 miles after 7 hours.
