Question 29012: I hope you can help me. I am having a little trouble with this word problem.
" A ski lift takes a skier up a slope at 50m/min. The skier then skis down the slope at 150m/min. If one round-trip takes 24 min, how long is the slope?"
I know I need to use the formula of d=rt, but I'm not sure how to write out the equation.
Thank you,
Jackie

You can put this solution on YOUR website!
(D/50)+(D/150)=24 OR (3D/150)+(D/150)=24 OR 4D/150=24 OR 4D=3600 OR D=900METERS
PROOF (900/50)+(900/150)=24 OR 18+6=24 OR 24=24.
