Margo walks to her friend's house in 10 minutes. Using the same route, it takes Margo 20 minutes to get back home. If her average walking rate for the entire trip is 4 miles per hour, how many total miles did she walk?

Margo walks 1 mile

Step-by-step explanation:

Given that;

Margo walks to her friend's house in 10 minutes.

Using the same route, it takes Margo 20 minutes to get back home.

Total walking rate = 20+ 10 = 30 minutes

The average of her walking rate for the entire trip is 4 miles per hour

i.e 30/2 minutes = 4 miles/hr

15 minutes = 4 miles/hr

Let x be the total number of miles that Margo walk;

So;

15 minutes × x  = 4 miles/hr

15 minutes × x = 4 miles/ 60 minutes

x  = (4 miles/ 60 minutes) × 15 minutes

x  = 1 mile

Thus, Margo walks 1 mile

Margo walks 1 mile

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
