Question 1194355
A man traveled a distance of 960 kilometers by ship to an island. He returned by plane. The rate of the plane was 20 times the rate of the ship. He spent 42 hours on the trip. Find the rate of the ship and the rate if the plane.
--------------
The ratio of the speeds is 20:1, so the time spent on each is 20:1 also.
42 total at 20:1 ---> 40 hours and 2 hours
Divide 960 by 40 and by 2
