Small tug boats pull cruise ships up and down rivers to prevent them from grounding. Cruise ships anchor 22 km away from the riv

er port. A tug boat can travel 20 km downstream in the same time it takes it to travel 10 km upstream. If the speed of the current is 5 km/h, calculate the time it takes for the tug boats to travel upstream from the cruise ship to the river port.

Answer:

2.2 hr

Step-by-step explanation:

Let the speed of the boat in km/h be x.

Then, the speed downstream is (x+5), and the speed upstream is (x-5).

We know the speed downstream is twice the speed upstream, so

x+5=2(x-5) \\ \\ x+5=2x-10 \\ \\ x=15

This means the speed upstream is 10 km/h. Thus, to travel 22 km, it will take 2.2 hrs.

Write two equivalent expressions to represent the area of the rectangle below.
Goshia [24]

Answer:

A=(n-3)2\ units^2

A=(2n-6)\ units^2

Step-by-step explanation:

we know that

The area of rectangle is equal to

A=LW

where

L is the length of rectangle

W is the width of rectangle

In this problem we have

L=(n-3)\ units\\W=2\ units

substitute

A=(n-3)2\ units^2

Apply distributive property

A=2(n)-2(3)

A=(2n-6)\ units^2
