Answer is 90 miles in 2 hours

Step by step

I like the cross multiply method for this. See attached picture with example.

We know she drove 30 miles / 40 minutes

We want to know “x” miles / 120 minutes ( equivalent of 2 hr)

Put into your equation

30/40 = x / 120

40x = 3600

X = 90 miles in 2 hours
