A 10 foot rope ladder hangs over the side of a boat with the bottom rung on the surface of the water. The rungs are one foot apart, and the tide goes up at the rate of 6 inches per hour. How long will it be until three rungs are covered?

Answer:

4 hrs

Step-by-step explanation:

1 foot = 12 inches

The rungs are 1 ft apart, so it means yung 3rd rung is 2 ft from the surface of water kasi yung first rung is nasa tubig na...

6 inches per hour- 2 hours ang kailangan para umabot sa 2nd rung( since 1 ft= 12 inches)...another 2 hours para umabot sa 3rd rung

2 hrs + 2 hrs= 4 hrs
