Keisha the trainer has two solo workout plans that she offers her clients: Plan A and Plan B. Each client does either one or the
other (not both). On Wednesday there were 2 clients who did Plan A and 3 who did Plan B. On Thursday there were 6 clients who did Plan A and 5 who did Plan B. Keisha trained her Wednesday clients for a total of 6 hours and her Thursday clients for a total of 12 hours. How long does each of the workout plans last?
If he goes 140 miles in 2 hours, then in 6 hours he would go 420 miles. 420 miles is not equivalent to 490 miles, so he would not reach his destination on time.
