It takes avery 3/4 hour to paint 1/5 of a painting. at this rate, how long will it take her to complete the painting?

It will take Avery 3 hours and 45 minutes to complete the painting.

Step-by-step explanation:

Time that it takes Avery to paint 1/5 of a painting = 3/4 hour

How long will it take her to complete the painting?

Time that it takes Avery to paint 1/5 of a painting = 3/4 * 60

Time that it takes Avery to paint 1/5 of a painting = 45 minutes

Time that it takes Avery to complete the painting = 45 minutes * 5

Time that it takes Avery to complete the painting = 225 minutes

Time that it takes Avery to complete the painting = 225/60

Time that it takes Avery to complete the painting = 3 hours and 45 minutes

It will take Avery 3 hours and 45 minutes to complete the painting.

It will take 3.45 hours to complete a painting

Explanation:

Given

It takes every ¾ hour to paint 1/5 of a painting

Let us consider complete painting to be 1

According to the principle of unitary method,

1/5 of painting = ¾ hour

Complete painting =  

=  (3/4)*5 = 15/4 hours

15/4 hours = 3.75

Hence, it will take 3.45 hours to complete a painting

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
