Jamal has two friends that will join him on a walkathon. One of his friend has been training and can walk 2km/hr faster than Jamal. The other friend can walk 1km/hr slower than Jamal, create an algebraic model to determine the total time it will take the 3 friends to complete the walk.

I think we need to know Jamal's speed.
Answered by M
we are not given his speed. He is expressed as "x".
and the 1st friend is 2+x
and the second is 1-x
