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

matrenka [14]

Answer:

After 900 minutes

Step-by-step explanation:

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

$45mph=45m/60min=0.75m/min$

$36mph=36m/60min=0.6m/min$

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

$D_1=0.75t$ (for 45mph ship)

$D_2=162+0.6(t-45)$ (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.

The store brought a pair of shoes for 40$ and sold it for 50$. What percentage was the markup?

PSYCHO15rus [73]

Answer:

20%

Step-by-step explanation:

You would do 40/50 and then 40/50 is also 80/100. Then you'd take the remainder and that'd be the mark up price.
