How far must she drive to reach destination?

Question

Merritt is driving to Ohio. On her map, she is 7 3/4 inches away. The scale of the map is 1/2 inch = 50 miles How far must she drive to reach destination.

Answer 1

Susan, we can set up a ratio.

 

1/2:50 = 7 3/4:x

 

If we cross multiply, we get x/2 = 387 1/2, so x = 775 miles.

 

Hope this helps!
