assistant
How many miles does the dog run in one minute? ** The dog runs .4 miles per minute because 24 / 60 = <<24/60=.4>>.4
How many miles does the rabbit run in one minute? ** The rabbit runs .25 miles per minute because 15 / 60 = <<15/60=.25>>.25
How many minutes does the dog have to catch up to the rabbit? ** We know that .4(Number of Minutes) = .25(Number of Minutes) + .6
How many minutes does the rabbit have a head start? ** Therefore .15(Number of Minutes) = .6
How many minutes does the dog have to catch up to the rabbit? ** Therefore (Number of Minutes) = 4
