In 22 minutes, a conveyor belt moves 600600 pounds of recyclable aluminum from the delivery truck to a storage area. A smaller belt moves the same quantity of cans the same distance in 88 minutes. If both belts are used, find how long it takes to move the cans to the storage area.

1.6 minutes = 1 minute and 36 seconds

Step-by-step explanation:

(Assuming that the correct values are 2 minutes, 600 pounds and 8 minutes)

The first belt can move 600 pounds of material in 2 minutes, so it can move 300 pounds per minute

The smaller belt can move the same 600 pounds the same distance in 8 minutes, so it can move 75 pounds per minute.

If we use them together, they can move 300+75 = 375 pounds of material per minute.

If we want to move 600 pounds of material, we can solve that using rule of three:

375 pounds -> 1 minute

600 pounds -> x minutes

375/600 = 1/x

x = 600/375 = 1.6 minutes = 1 minute and 36 seconds

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
