Agirl can ski down a hill 5 times as fast as she can climb up the same hill. if she can climb and ski down the hill in a total of 9 minutes how many minutes does it take for her to climb up the hill?

Lets say we represent the amount of time she could ski.

So it would be x = the amount of time she skis

And 5x would represent how long it took her to climb

and she took 9 minutes to climb.

So what we would do first is put it in a equation like this

x + 5x = 9

Now we have 6x = 9

Divide 9 by 6x, and we get x = 15

So multiply 1.5 by 5 and the answer would be 7.5

Hopefully this helped. :)
