One hour after Yolanda started walking from X to Y, a distance of 45 miles, Bob started walking along the same road from Y to X. If Yolanda's walking rate was 3 miles per hour and Bob's was 4 miles per hour, how many miles had Bob walked when they met?
The correct answer is 24...but why?🙁
 
she walked 3 already
so
42 = a(3) +a(4)
42=7a
a=5
so it took 6 hours for them to meet

bob was a(4)
6 hours * 4 mph = 24

is this your homework?
i need to go study triple integrals now

You had to learn that stuff at some point too... There's always someone doing something harder.
