Question

Jim began a 130 mile bike trip to build up stamina for a triathlon. Unfortunately, his chain broke, so he finished the trip walking. The whole trip took 6 hours. If Jim walks at 3 mph, and rides at 35 mph, how long was he on the bike?

Answer 2

maybe @confluxepic could help...?

Answer 3

ok thanks

Answer 4

You need two equations again.

Answer 5

W=walking and R=riding

Answer 6

Good

Answer 7

3w +35r = 6?

Answer 8

3w + 35r would reflect the distance you went

Answer 9

Is that correct?

Answer 10

No..

Answer 11

so 3x+35r=130

Answer 12

Good...now what will be the second equation that represents time on the bike?

Answer 13

so do i need to use the substitution method for these two equations?
3w + 35r = 130
w + r = 6

Answer 14

You got this....very good

Answer 15

w = 6-r so
3(6-r) +35 r = 130
18-3r + 35r = 130
18 +32r =130
32r + = 112

Answer 16

r = 3.5

Answer 17

so he rode for 3.5 hours and walked for 2.5

Answer 18

Thanks for the help :) I think I will be able to do it on my own next time!

Answer 19

Always plug the numbers back in the equation to check your answers..very good and good luck
