a family goes on a trip that 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 driven in how far did they drive after several hours

Let's use the following variables:

H = number of hours driven
D = total amount of miles driven

The equation representing the relationship between H and D is:
D = 65H

If the family drives for several hours, say for 5 hours, we can substitute H = 5 into the equation to find out how far they drove:
D = 65(5)
D = 325 miles

Therefore, after driving for 5 hours, the family drove 325 miles.
