Question

Please help with this one too... solve
Ed and Rick leave the same point at the same time. Ed is bicycling west at a rate of 2 mi/h faster than Rick, who is traveling south. After one hour, they are 10 miles apart. How fast is each person traveling?

Answer 1

Can somebody help me???

Answer 2

S1² + S2² = 100 mi
(x* t)² + ( y *t)² = 100
x² + ( x+2 )² = 100
-> 2 x² + 2x + 4 = 100
=> 2x² + 2x - 96 = 0

Can you continue to solve for x which is velocity of Rick!

Answer 3

Uh... I dont really get it...

Answer 4

I mean:
-> 2 x² + 4x + 4 = 100
=> 2x² + 4x - 96 = 0

Answer 5

will it be (2x-12)(x+8)?
