Amouse can travel 8 miles per hour. write an equation to find the total distance "d" a mouse can travel in "h" hours.

d = 8h

Step-by-step explanation:

Given that the mouse can travel 8 miles per hour, we can use multiplication as the operation to use when calculating for the amount of miles traveled over time.  For example, in two hours, the mouse would have traveled 16 miles: 8 x 2 = 16 and in three hours, the mouse would have traveled 24 miles:  8 x 3 = 24.  Since the total number of miles is equal to the distance traveled, we use 'h' for the number of hours and 'd' for distance to get:

d = 8h

a. is correct
