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.
