Answer:
Step-by-step explanation:
Expand with the distributive rule:
Add 4/3 to both sides:
Subtract 4x from both sides
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

Answer:
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.
