mei is competing in a remote control car race she can complete 15 laps in 24 minutes.
find how long it will take mei to finish 20 laps if she keeps the same speed
To find out how long it will take Mei to finish 20 laps at the same speed, we can set up a proportion using the given information.
15 laps / 24 minutes = 20 laps / x
Cross multiply to solve for x:
15 * x = 24 * 20
15x = 480
x = 32 minutes
Therefore, it will take Mei 32 minutes to finish 20 laps at the same speed.
darrel wants to see how much water is wasted by his leaky faucet he put a 4 gallon bucket under the faucent after 24 hours the bucket was full
if the same amount of water leaks each hour, how much water will be in the bucket after 60 hours
If the same amount of water leaks each hour and the 4-gallon bucket was full after 24 hours, then the leaky faucet is leaking 4 gallons every 24 hours.
To find out how much water will be in the bucket after 60 hours, we can set up a proportion using the leak rate:
4 gallons / 24 hours = x gallons / 60 hours
Cross multiply to solve for x:
4 * 60 = 24 * x
240 = 24x
x = 10 gallons
Therefore, after 60 hours, the 4-gallon bucket will contain 10 gallons of water leaked from the faucet.
