Answer:

10.30p.m - 6.00a.m = 4.30

11.00p.m - 6.00a.m = 5.00

11.00p.m - 7.00a.m = 4.00

4.30 + 5.00 + 4.00 = 13.30

or you could do

4.30 + 4.00 = 8.30

8.30 + 5.00 = 13.30

13.30 = 1.30

I don't know if this is right, but i tried my best to help.

A plane traveled 240 miles. The trip was with the wind. It took 3 hours. The trip back was into the wind. The trip back took 6 h

sveta [45]

Answer:

Plane speed is 60 miles/hour

Wind speed is 20 miles/hour

Step-by-step explanation:

Lets suppose the speed of the plane in still air is s and speed of the wind is w and since speed in the formula below equals speed of the plane plus the wind's speed so speed=s+w for this journey with the wind

$Speed=\frac{Distance}{Time}$

$Distance=Speed*Time$

For the first journey the trip with the wind:

$Distance=Speed*Time\\240=(s+w)(3)\\240/3=s+w\\s+w=80$

Here we got our first equation for the second equation we use the information from the second trip which was into the wind. Which means the speed here would be speed=s-w

$Distance=Speed*Time\\240=(s-w)*6\\240/6=s-w\\s-w=40$

so now we got our two equations adding both equations would result into the following:

$s+w=80\\s-w=40\\2s=120\\s=60$

so speed of the plane is 60 miles/hour put the value of s in any our two equations to calculate the wind speed, lets take the first equation:

$s+w=80\\60+w=80\\w=80-60\\w=20$

so the wind speed is 20 miles/hour

Steven needs to type a 2000 word document for work. If he can type 125 words in 2 minutes, how long will it take to type the who

Dimas [21]

Answer:

32 minutes

Step-by-step explanation:

This can be calculated with some good old division and multiplication:

Step 1 - Divide the word count by the number of words every 2 minutes:

2000 ÷ 125 = 16

Step 2 - Multiply the 16 by the 2 minutes:

16 * 2 = 32

The 16 is the number of words it would take and multiply the 16 by 2 will tell us the number of minutes it would take for the whole document to be written.

So it would take him 32 minutes.

Hope this helps!
