It takes 41 minutes for 9 people to paint 9 walls. how long doe sit take for 14 people to paint 14 walls

41 minutes

When 9 people are painting 9 walls, there are the same amounts of people and walls.  This means all of the walls are being painted at the same time, with one person painting each wall.

The same applies to 14 people painting 14 walls.  All of the walls are being painted at the same time, with one person painting each wall.

Even if there was only one person painting one wall, it would take 41 minutes.

41 minutes

Step-by-step explanation:

It takes 41 minutes for 9 people to paint 9 walls.

9 walls/ 9 people = 1 wall / person

So it takes 41 minutes  for 1 person to paint 1 wall

14 walls/ 14 people = 1 wall / person

It will take the same amount of time

41 minutes

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
