The estimated time it takes both teams to seal a parking lot would be 14 hours.

<h3>How to calculate the time that both groups take?</h3>

To calculate the time that both groups take to seal the parking lot, we must take into account the hours that each group takes and perform the following operation:

  • 12 hours + 16 hours = 28 hours
  • 28 hours ÷ 2 groups = 14 hours

Based on the above, it can be inferred that if both groups work together they can complete this task in an average of 14 hours.

RideAnS [48]

Answer:

The candle must burn at 2cm per hour in order to be 6cm tall after 4 hours. I know this because the candle has to burn 8cm in 4 hours and that amounts to 2cm per hour.

Step-by-step explanation:

Lets solve!

We have to find out how much of the candle needs to be burned!

14cm - 6cm = 8cm

The candle must burn 8cm in 4 hours!

Lets find out how much the candle burns in 1 hour.

\frac{8cm}{4hours}= 2cm per hour

The candle must burn at 2cm per hour in order to be 6cm tall after 4 hours. I know this because the candle has to burn 8cm in 4 hours and that amounts to 2cm per hour.

Woohoo, We did it! <u>Would you like to mark my answer as brainliest?</u> I would love that!
