The question is relating Rhonda's distance travelled and time taken
If 45 miles = 3 hours
Then, 1 mile = 3/45 hours

Therefore, it will take Rhonda 1/15 hours to travel 1 mile.
By the Pythagorean Theorem:
L^2=20^2+15^2
L^2=400+225
L^2=625
L=25 m
355, and any greater number that's less than 365, can.
The maximum is 5, and the minimum is 1. The max. is in the are on the same side, which combines forces of 3 and 2. The min. uccors when they are on opposite sides.
