    Velocity
In summary, John starts his bike trip at 18km/hr and after two hours, Derek follows on his motorcycle at 72km/hr. The problem is solved by setting their distance equations equal to each other and solving for time. After finding the time, you can compute the distance traveled by either John or Derek at that time.

Express d(t) for each moving object.

Set them equal.

Solve for t.

Compute d(t) at that time.
 
  • #3
V=x/t.So use this formula to reach "How many meter john travel in 2 hours"
Lets call it ##x_1##.Now the time pass same both of them.
##x_1##+VJohntJohn=VDerektDerek
Use this equation to find solution.
