Question 304792
How much farther can a boat traveling at a rate of 15 kilometers per hour for x hours travel than a second boat traveling at a rate of 18 kilometers per hour for x-3hours?
---
Distance = rate*time
1st: 15x miles
2nd: 18(x-3) = 18x-54
-------------------------------
Equation:
(18x-54) - 15x = 3x-54 miles further.
