Answer:

100 minutes = 1hour 40 minutes

Step-by-step explanation:

25 students in the class.  1/5 of them have blue eyes.

So    1/5(25) = 25/5 = 5

Therefore 5 students have blue eyes.

Next problem

1 hour = 60 minutes

so  1/3 (60)  =20 minutes per wash

Now Sam wash the dishes 5 times a week .  How many minutes does he spend washing dishes?

5 × 20 minutes  = 100 minutes or 5(1/3)(60) = 100 minutes = 1 hour 40 minutes.
