Answer:
18 hours.
Step-by-step explanation:
Given :- When fire is in the water, clock is 8.5 seconds slow and when fire is not in the water, clock is 5.1 seconds fast.
To find :- Time for which fire is in the water.
Solution :-
Let the amount of time for which fire is in the water be x hours.
So, time for which the fire is not in the water = 48 - x.
It is given that, when fire is in the water, clock is 8.5 seconds slow and when fire is not in the water, clock is 5.1 seconds fast.
Acc. to the question,
8.5 × x = 5.1 × ( 48 - x )
⇒ 8.5x = 244.8 - 5.1x
⇒ 8.5x + 5.1x = 244.8
⇒ 13.6x = 244.8
⇒ x = 244.8 ÷ 13.6
⇒ x = 18 hours
Therefore, for 18 hours fire is in the water.
