A watch loses x minutes every y hours, at this rate how many hours will the watch lose in one week?
2 answers:
Minutes lost hourly is x/y. One week has 24 * 7 = 168 hours. 168x / y would be minutes lost weekly, and (168/60) (x / y) = (42/15)(x/y) would be hours lost weekly.
Answer:
10080y/x hours
Explanation:
The rate = x/y
x is in minutes
y is in hours.
How many hours will it lose in one week.
Converting one week to minutes.
One week has 7 days: a day has 24 hours.
In one week we have 24×7= 168 hours
60 minutes make one hour : in 168 hours we have
60×168=10080 minutes
Hours lost at the same rate = total minutes/ rate
= 10080/(x/y)
Hours lost= 10080y/x hours
