Question

Given that a truck can drive 25 miles with four gallons of gas, how many gallons does it need to drive 125 miles?

Answer 1

This is really easy if you think about it :) Ok do you just want the answer or step by step stuff?

Answer 2

Steps

Answer 3

what no! @OrangeMaster

Answer 4

Oh yeah, 20

Answer 5

Well, you're taking both variables (gas and miles) and multiplying them by 4. So, it would be 20 gallons.

Answer 6

125/5=5

5*4=20 gallons.

Answer 7

Thanks @shoplovepc, I really messed up there.

Answer 8

Don't I have it right now?

Answer 9

Ok

So first let's look at our FACTS
we KNOW 100% that:

- the truck can drive 25 miles with four gallons of gas

we WANT to know:

- how many gallons the truck will need for 125 miles

So let's start solving it

So we want to know how many times there is 25 in 125, since we know that he needs 4 gallons for 25 miles

so

125/25 = 5

And we know that for every 25 miles he needs 4 gallons so

5 * 4 = 20

So he needs 20 gallons for 125 miles.

Answer 12

Well, looks like @shoplovepc did a much better job than we did at explaining, @OrangeMaster. Lel

Answer 13

Thanks again @shoplovepc. I just kept it simple, there wasn't much explaining that needed to be done.

Answer 14

It was just simple math.

Answer 15

Any more questions?

Answer 16

@OrangeMaster haha thanks :) it is pretty simple but it always helps to explain and trains my brain sooooo

Answer 17

Ya one more question

Answer 18

At a university, the number of units for a class varies directly as the number of hours each student is expected to work in the class. A four-unit class expects each student to dedicate 10 hours a week to studying for the course. How many hours should a student expect to study for a particular class that is worth six units?

Answer 19

@OrangeMaster you want to help with this one?

Answer 20

You have an idea yet, I'm still thinking.

Answer 21

I'm actually also still thinking

Answer 22

I think I got it.

Answer 23

If you divide 10 by 4, you get 2.5

Answer 24

oh so 15?

Answer 25

So what I did next is went through numbers until I got 2.5 again. If you divide 15 by 6 you get 2.5 doesn't that make sense.

Answer 26

Yes, exactly.

Answer 27

so 15 hours for a six unit class @OrangeMaster smart I can't believe it took me so long to get that

Answer 28

It took me a minute too, until I figured it out.

Answer 29

Thanks now I understand
