Question

The principal at Richmond High School is planning the graduation ceremony for this year. Last year, it took her 50 minutes to hand out diplomas to 250 graduates. This year, there are 300 graduates. If the principal hands out diplomas at the same rate, how long will it take to hand out diplomas at this year's ceremony?

Answer 2

Use unitary method.
250/50 = 5.
This means that in 1 minute 5 graduates are handed over a diploma.
Therefore,
300/5 = 60 minutes
The answer is 60 minutes or 1 hour.
