A tank sprung a leak in the water level started drop from 24.8 m at a rate of 2 m/h. Right and solve an equation to determine ho

malfutka [58]

Answer:

8 hours.

Step-by-step explanation:

The initial water level is 24.8 meters, and the rate of water level drop is 2 meters/ hour, that means after $t$ hours the water level $L$ will be

$L =24.8-2t$

Now we want water level to be 8.8 meters, I.e $L=8.8m$ , therefore, we have:

$L=8.8=24.8-2t$

we solve the equation for $t$ :

$8.8=24.8-2t\\8.8+2t=24.8\\2t=24.8-8.8\\2t=16\\\\\boxed{t=8}$

it will take 8 hours for the water level to drop to 8.8 meters.
