The faucet drips 2 drops per second, 0.05 ml per drop. Xiao Ming didn't tighten the faucet after washing his hands. When Xiao Ming left for 4 hours, How many milliliters of water is dripping from the tap

The faucet drips 2 drops per second, 0.05 ml per drop. Xiao Ming didn't tighten the faucet after washing his hands. When Xiao Ming left for 4 hours, How many milliliters of water is dripping from the tap

First unit conversion, two drops per second, 0.05 ml per drop, then 0.1 ml per second. Therefore, 2 * 0.05 = 0.1 ml
4 hours converted into minutes, 4 * 60 = 240 (minutes)
240 * 60 = 14400 (seconds)
14400 * 0.1 = 1440 (ML)
1440 is expressed as the cubic power of 1.44 * 10 by scientific counting method

The tap that can't be tightened will drip 2 drops of water every second, 0.25 ml per drop. Xiao Ming didn't tighten it when he washed his hands. When he left X minutes, the tap dropped y
The tap that can't be tightened will drop 2 drops of water every second, 0.25 ml per drop. Xiao Ming didn't tighten it when he washed his hands. When he left X minutes, the tap dropped y milliliters of water, so the analytic expression of the function between Y and X is____________
Notice that the next minute

The total time is: X minutes = 60 * x seconds
The total amount of water dropped is: 60 * x seconds * 2 drops / second = 120 * x drops
The total amount of water is 120 * x drops * 0.25 ml / drop = 30 * x ml
Namely: y = 30 * x
*It is a multiply sign

According to the survey, a tap that is not tightened at home drips 40 drops in one minute, 27 ml in three minutes, and how many ml in one hour? How many liters of water drop a day and a night?

Because 27 △ 3 = 9 (ML) 1 hour = 60 minutes, 60 × 9 = 540 (ML) 1 day = 24 hours, 540 × 24 = 12960 (ML) = 12.96 L. A: 540 ml of water drops in 1 hour; 12.96 l of water drops in a day and night
