Problema Solution
Jason and Steve are 45 miles apart on the canal path and start to ride toward each other . Steve rides twice as fast and they meet after to hours. How fast does Steve bike ?
Answer provided by our tutors
let
x = the speed of Jason
y = the speed of Steve
d = 45 miles the distance between them
t = 2 hours they meet after 2 hours
Steve rides twice as fast
y = 2*x
in 2 hours
the distance that Jason crossed + distance that Steve crossed = d - distance between them
2*x + 2*y = 45
by solving the system of equations
y = 2*x
2*x + 2*y = 45
we find
y = 15 miles per hour
Steve's speed is 15 miles per hour.
