Over the summer in Albany, New York, the depth of the local reservoir decreased 15 inches. If the water depth decreased by 3 inches each week, how many weeks did it take for this change to occur?
HELP ASAP THX
The answer would be 5 weeks, because you can divide the 15 inches by 3 inches lost per week.
Think of it as losing three inches every week for five weeks, so what times 3 would be equal to 15?
5
thx for helping but i already figured it out but thx and it's right
Alright. Just ask again anytime you need help!
To determine how many weeks it took for the depth of the reservoir to decrease by 15 inches, we can use division. We need to divide the total change in depth (15 inches) by the rate of change per week (3 inches). The result will tell us the number of weeks it took for this change to occur.
To calculate this:
15 inches ÷ 3 inches per week = 5 weeks
Therefore, it took 5 weeks for the depth of the local reservoir to decrease by 15 inches over the summer in Albany, New York.
