Answer:
Between Sean swimming 475 meters and Callie swimming 0.62 kilometer, Callie swam farther.
General Formulas and Concepts:
Pre-Algebra
Step-by-step explanation:
Step 1: Define
Identify given.
Sean swam 475 meters.
Callie swam 0.62 kilometer.
Step 2: Convert
Recall that 1 kilometer is equal to 1000 meters.
0.62 kilometer = 620 meters.
Step 3: Compare
We can see that 620 meters is bigger than 475 meters.
∴ Callie swam farther than Sean.

Topic: Pre-Algebra
We are given two peoples and their distance which they swam, and we need to find who swam farther, so let's start by coverting either sean's distance in km or Callie's distance in metres, also, maybe you need both, so I will do from both
i) As we know, 1km = 1000m
So, Callie swam (62/100)×1000 = 620 metres, also Sean swam 475 m, so as 620 m > 475 m, so Callie swam farther
ii) As we know, 1m = (1/1000) km
So, Sean swam (1/1000)×475 = 0.475 km, also Callie swam 0.62 km, so as 0.62 km > 0.475 km, so Callie swam farther
We are done!
