Diego and Lin are drinking milkshakes. Lin starts with 12 ounces and drinks 1/4 an ounce per second. Diego starts with 20 ounces

sammy [17]

Answer:

Lin = 48 seconds

Diego = 30 seconds

Step-by-step explanation:

Hi, to answer this question we have to divide the total ounces of drink by the amount that each one drank per second, for each case.

Mathematically speaking:

Lin = 12 ounces / (1/4) ounces/second = 12/ (1/4) = 48 seconds

Diego = 20 ounces / (2/3) ounces/second = 20/ (2/3) = 30 seconds
