Answer:
A. Theo drove 57 miles and Lex drove 62 miles in 1 hour.
B. Lex drove faster. We know this because in order to figure out how many miles each drove per hour you need to find there individual rate. Which is 228/4 and 186/3. You want to divide using the hours so you generate a response where 1 hour is the only thing left. Thus giving you mph (miles per hour). Lex is drove 5 miles more in an hour than Theo leading us back to who drove faster. Lex did.
Hope this helps!
