## Homework Statement

Distance = Speed / Time

Speed = Distance / Time

Distance = Speed * Time

Also breaking up "chunks of time" in an hour

2 of 30 mins

3 of 20 mins

4 of 15 mins

5 of 12 mins

10 of 6 mins

12 of 5 mins

15 of 4 mins

20 of 3 mins

## Homework Equations

1) An example of an easy question to do mentally would be:

Speed of 24 mph, how far would you travel in 1 hour 15 minutes?

2) You travel

*111 miles*. How much fuel will you need if you burn

*36 kgs per hour*, and are traveling at

*148 mph*?

-Need help finding the quickest way to solve.

## The Attempt at a Solution

0.25 of 24 is 6. Therefore,

**24+6 = 30 miles**

**I'm wondering if anyone knows the quickest most efficient way to solving questions such as:**

What speed covers 18 miles in 54 minutes

And if there's a simple way to do it mentally?

I appreciate your replies!

This site has some sample tests including the fuel consumption questions too.
