Abigail rides her bike with a constant speed of 12 miles per hour. how far can she travel in 45 minutes?

If she rides at 12 miles per hour, we know that 45 minutes is three quarters of an hour, therefore just workout:

3/4 x 12 = 9

So she would travel 9 miles in 45 minutes.

3/4*12=9 so she will travel 9 miles in 45 minutes
