Elena and Jada are 12 miles apart on a path when they start moving towards each other Elena runs at a constant speed of 5 miles per hour and Jada walks a constant speed of 3 miles per hour how long does it take untill Elena and Jada meet? please explain answer. Thank you!

if you really want to figure this out you make an equation to solve for the time
let's let
x = time from Elena to Jada and
x = time from Jada to Elena
12 then the equation
12 = 5x +3x
would help figuring out their distance say for one of them
12 = x(5+3)
12/8 = x
1.5 = x
1. 5 hours they will meet up
