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.

Answer:
15 m
explanation:
Let AB and CD be the pole and tower respectively. Let CD=h Then ∠DAC=60 ∘ and∠DBE=30 ∘ Now CA CD =tan60 ∘ = 3 ∴CD= 3 CA⇒ 3 h =CA Again BE DE =tan30 ∘ = 3 h ∴(h−10)= 3 BE = 3 CA ...[∵BE=CA] = 3 h/ 3 = 3 h ⇒3h−30=h⇒2h=30⇒h=15
Hence, height of the power =15 m
