once a month, volunteers from the green sea club clean up litter at the beach. last month, the volunteers picked up 8 pounds of trash in 4 hours. this month, the same group of volunteers will spend 3 hours picking up trash. if they pick up trash at the same rate, how many pounds of trash should the volunteers pick up this month? pounds
Answer
Explanation:
Step1: Calculate the rate of trash - picking
The rate $r$ is calculated by dividing the amount of trash picked up by the time spent. Last month, they picked up 8 pounds of trash in 4 hours. So the rate $r=\frac{8}{4}=2$ pounds per hour.
Step2: Calculate the amount of trash this month
This month, they will spend 3 hours picking up trash at the rate of 2 pounds per hour. So the amount of trash $a = r\times t$, where $r = 2$ pounds per hour and $t = 3$ hours. Then $a=2\times3 = 6$ pounds.
