Question

Larissa eats of a 1.5-pound bag of goldfish in of an hour. If she eats goldfish at a constant rate, how long, in hours, would it take her to finish a 5-lb box of goldfish?

Answer 1

(3/5)(3/2) = 9/10 lbs eaten in 5/6 of an hour

(9/10)/(5/6) = 5/t

Cross multiply!

(9/10)t = (5/6)(5)

(9/10)t = 25/6

t = 250/54 = 4 34/54 = 4 17/27 hours
