Answer: 7 hours 30 mins
Explanation:
1. Daniel needs to spend the same time in Go-Kayak, and Fun Kayaking in order for both charges to be equal. We will keep that amount of time as X.
2. Write it as an equation. 15 + 4x = 6x
3. Now, solve the equation. 15 = 2x. 15/2 = x
4. In other words, X is 15/2 hours, which is 7 hours and 30 mins.
Word Problem: 15 + 4x = 6x
