You can put this solution on YOUR website! Jonathan and Tim started Running toward each other. Jonathan at 16 yards per minute and Tim at 18 yards per minute. If they were 1,360 yards apart when they started running, how long did it take for them to collide?
:
Let t = time for them to collide (in minutes)
:
Write a dist equation: Dist = speed * time
:
18t + 16t = 1360
34t = 1360
t =
t = 40 minutes
:
:
Check solution, find the distance of each:
18*40 = 720
16*40 = 640
------------
total =1360
