help here would be greatly appreciated. i'm having a hard time setting up this equation algebraically.

this is what i understand:

- the entire trip consists of 2 parts (below)

1) traveling distance of Y at X mph

2) traveling distance of 40-Y @ 1.25X mph

*Note: Y must be < X

- D=RT. BUT you want to know T, so T = \(\frac{D}{R}\)

JeffTargetTestPrep, can you please explain why you did the below?

y/x + (40 – y)/(1.25x) is what percent of 40/x ?

[y/x + (40 – y)/(1.25x)]/(40/x) * 100 = ?

The way I translated the first statement is: y/x + (40 – y)/(1.25x) = \(\frac{X}{100}\) * (\(\frac{40}{X}\))
