Question

Larissa eats 3/5 of a 1.5-pound bag of goldfish in 5/6 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

Answer:

it will take Larissa 4 17/27 hours to finish 5lbs of goldfish

Step-by-step explanation:

1.5 pound = 1 1/2 pound equivalent to 3/2 pounds

3/5 of a 1.5-pound

= 3/5 × 3/2 pounds

= 9/10 lbs of goldfish eaten in 5/6 hours

how long, in hours, would it take her to finish a 5-lb box of goldfish?

Find the ratio

9/10 lbs of goldfish : 5/6 hours = 5lbs of goldfish : t hours

9/10 ÷ 5/6 = 5 / t

Solve for t

9/10 × 6/5 = 5 / t

54 / 50 = 5 / t

Cross multiply

54 × t = 50 × 5

54t = 250

Divide both sides by 54

t = 250 / 54

= 4 34/54

= 4 17/27 hours

Therefore, it will take Larissa 4 17/27 hours to finish 5lbs of goldfish
