Question

I can't seem to solve this problem. I have to make an equation to solve this but i don't know how to make an equation for this problem! Please help.

Answer 1

Well each ladder has 30, and then it depends on how each person climbs their ladder. One climb at the rate of -2 per second. The other climb at the rate of 1 per second. Just x is equal to 1, that's why I didnt put 1x.
Equation: 30 + -2x = 30 + x
