The train station clock runs too fast and gains 8 minutes every 10 days. How many minutes and seconds will it have gained at the end of 7 days

At the end of 7 days, it will have gained 5 minutes and 36 seconds.

Step-by-step explanation:

This question can be solved using a rule of three.

It gains 8 minutes every 10 days. How much does it gains every 7 days?

7 days - x minutes

10 days - 8 minutes

Each 7 days, it gains 5.6 minutes. That is, it gains 5 full minutes, plus 0.6 = 60% of a minute, in seconds.

A minute has 60 seconds. 0.6*60 = 36

So

At the end of 7 days, it will have gained 5 minutes and 36 seconds.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
