Question

4. In 2 days and 20 hours a watch gains 20 sec. Find, how much time the watch wil take to gain 35 sec.​

Answer 1

Answer:

We know that. 2 days 20 hours = 2×24+20=48+20=68 hours.

Time in which 20 sec are gained = 68 hours.

so that time in which 1 sec will be gained = 68/20 hours.

Similarly the time in which 35 sec will be gained = 68/20×35 = 119 hours.

So we get = 119÷24days. = 4 days 23 hours
