Step-by-step explanation:
118 is the answer 238-120 = 118
200 times 40000 is 8000000.
200
x 40000
---------------
8000000
2.5 km because 1.5 is half of 3 and half of 5 is 2.5
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.
