Answer 1

Answer with explanation:

We have to make the following conversions:

a)

90 kilometers to meters.

We know that 1 kilometer=1000 meters.

Hence,

90 kilometers=90000 meters.

b)

250 centimeters to hectometers.

We know that:

1 centimeter=0.0001 hectometers.

Hence, 250 centimeter=0.0250 hectometer.
