how much does a watch gain or lose per day if its hand coincide every 64minutes???

Answer 1

How much does a watch gain or lose per day if its hands coincide every 64 minutes?

24 hours equals 24*60=1440 minutes. 1440/22 = 65 and 5/11 minutes.=> every 65 and 5/11 min, they coincide. Now the clock in question coincide every 64 minutes; therefore 24 hours in your clock means 64*22 minutes or 1408 minutes. So your clock should lose 1440-1408=32 minutes.

does this help

Answer 2

Answer:

32  8/11 min

Step-by-step explanation:

loss per hour = 65 5/11 - 64= 16/11

no of hours [of this clock]= 24 x 60 /64

loss per day = 16/11 x 24 x 60 /64

                     = 32 8/11 min
