Question

1. the greatest distance between earth and the sun during earth’s revolution is 152 million kilometers. what is this distance in megameters?

Explanation:

Step1: Recall the conversion factors

1 kilometer (km) = 1000 meters (m) and 1 megameter (Mm) = 1000000 meters (m), so 1 km=1000 m and 1 Mm = 1000000 m, then 1 km = 0.001 Mm.

Step2: Convert 152 million kilometers to megameters

152 million = 152000000. Multiply the number of kilometers by the conversion - factor. 152000000 km×0.001 Mm/km = 152000 Mm.

Answer:

152000 Mm
