Final answer:
Larissa eats goldfish at a rate of 2.0833 pounds per hour. It would take her approximately 2.4 hours to finish a 5-lb box of goldfish.
Step-by-step explanation:
The question involves Larissa eating 5/6 of a 1.5-pound bag of goldfish in 3/5 of an hour and asks how long it would take her to finish a 5-lb box of goldfish. To solve this, we need to determine her eating rate and then use it to calculate the time needed for a larger quantity.
First, we find the rate at which Larissa eats goldfish:
- She eats 5/6 of 1.5 pounds, which is 1.5 x (5/6) = 1.25 pounds.
- She does this in 3/5 of an hour.
Next, we calculate how many hours she would need to eat 5 pounds:
- Her eating rate is 1.25 pounds per 3/5 hour, which simplifies to 2.0833 pounds per hour (since 1.25 / (3/5) = 2.0833).
- For 5 pounds, we divide the 5 pounds by her eating rate: 5 / 2.0833 = approximately 2.4 hours.
Thus, it would take Larissa approximately 2.4 hours to finish a 5-lb box of goldfish.
