1 mile = about 1.61 km.

Multiply: 25,000 * 1.61 = ? km

1 km = 1,000 m

Multiply your km answer by 1,000.

To be more accurate for the meters --

1 mile = 1 609.344 meters

Multiply: 25,000 * 1,609.344 = ? m

kg = kilogram (measures mass)

km = kilometer (measures distance)

Yes. Follow the steps I gave you to find the answers.

The more accurate answer is 40,233,600 meters. But many teachers would probably accept the other answer, also.

Is that 40250000 is the right answer.
