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

Question

, and the total amount of miles driven, m
. How far did they drive after 7 hours?
Equation:

Miles driven:

Answer 1

To represent the relationship between the number of hours driven (h) and the total amount of miles driven (m), you can use the equation:

\[ m = 65h \]

This equation states that the total miles driven (m) is equal to the speed (65 miles per hour) multiplied by the number of hours driven (h).

To find out how far they drove after 7 hours, you can substitute \( h = 7 \) into the equation:

\[ m = 65 \times 7 \]

Calculating that gives:

\[ m = 455 \]

So, after 7 hours, they drove a total of 455 miles.
