The distance between port m and port n is 162m. a ship left port m with a speed of 45 mph. in 45 minutes another ship left port n and went towards the first ship with a speed of 36 mph. how long after the departure of the first ship will the two ships meet?

After 900 minutes

Step-by-step explanation:

when we convert the velocities of the ships into miles/ min we get

The equations determining the distances  of the ships from the port M (set at x=0) are

(for 45mph ship)

(for 36mph ship)

The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.
