The mass of a large adult male hippo is about 1,850,000 grams and the mass of a large adult female is about 1,525,000 grams.

What is the difference, in kilograms, between the masses of the adult male and female hippos?

Answer 1

So we want to know how long Maria's driveway is in kilometers if we know the length in meters. L=35.25m. To get the length in kilometers we need to divide the length by 1000 and so the length L= 0.3525km. And we want to know the difference in mass in kilograms between an adult male and female hippo. Mm=1850000 g = 1850 kg, Mf=1525000g=1525kg. Mm-Mf=325kg and that is the mass difference in kilograms.
