Make sure to read all of my instructions before answering a question! I gave you many tips, hints, and tricks to help you solve the problems.

Whenever you convert a number from kilometers to meters, you move the decimal to the right three places. 

km-kilometers
m-meters

(1 km = 1000 m)

Practice doing that with the measurements below!

3.52 km = ______m

6.78km =_____m

24.29km=_______m

754.79 km=__________m

0.528 km=______m

There are 12 zeros in 6 trillion (6 x 1012 or 6,000,000,000,000)

-Multiply the distance by 6 trillion to get the miles

-Multiply the miles by 1.6 to get the kilometers

I did the first one as an example.

Use the answers from the table above to answer Questions 12-13!

If astronauts travel in a spaceship to Sirius A and back, then how many miles would the astronauts travel?

To prepare for the astronauts’ trip to Sirius A, the engineers need to determine the amount of fuel needed for the trip there and back. The engineers know that they need 1,000 gallons of fuel for each 5,000 miles the spaceship travels. How many gallons of fuel will the spaceship need for the trip to Sirius A and back?
