During a rainstorm a pail collects 1/3 of an inch of water in 5/6 of a minute. At what rate is the pail collecting water?

Delicious77 [7]

Answer:

2/5 of an inch per minute

Step-by-step explanation:

You can set up the rate as $\frac{1/3}{5/6}$ . From here to find the amount of rain per minute, just multiply the numerator and denominator by 6/5 (The reciprocal of 5/6, so you can have one minute and see how much rains fills up in that time.)

You end with 2/5 of and inch per minute
