This is a simple problem which would explain how "rates” are useful. So useful that sometimes they decide whether a person is fit for a job or not!! To solve this we need the ratios of the number of words typed in a certain period of time.
Ratio (or rate) for Amita = 120 words60 seconds=2
Ratio for Balu = 80 words50 seconds=1.6.
Therefore, Amita types faster than Balu.
