The smaller spiral heats the water in 30 hours, and the larger in 20 hours. How long will it take to heat the water if we turn on both coils simultaneously and the smaller coil breaks down after 8 hours of heating?

Correct answer:

t =  14.6667 h

Step-by-step explanation:


1/30 · 8 + 1/20 · t= 1

3t = 44


t = 44/3 = 14.66666667

t = 44/3 ≈ 14.666667
