Can anyone tell me how to solve this problem?

Jack and joe are 150 miles apart in a straight line. Jack leaves from A at a speed of 30 miles per hour. Joe leaves from B at a speed of 50 miles per hour. When they meet each other, how far is joe from the starting point of Jack i.e, A.?

As it will take the same time for jack and joe to meet at some point

Therefore,

x/30 = (150-x)/50

x = 56.25 miles

Jack and Joe are moving towards each other, hence relative speed = 50 + 30 = 80 mph

Time taken to meet = 150/80 = 15/8 hr

Distance of meeting point from A = Distance travelled by Jack = 30*15/8
= 56.25 miles.

Using d = st,

for Jack, d = 30t
for Joe , (150-d) = 50t

d/(150-d) = 3/5 => 5d = 450-3d => d = 450/8 => 56.25 miles.
