CPM Homework Help : CCG Problem 5-35

While playing a board game, Mimi noticed that she could roll the dice $8$ times in $30$ seconds. How many minutes should it take her to roll the dice $150$ times?

Hint:

Write a proportion. Ratios should compare the $\frac{\text{(number of rolls)}}{\text{(number of seconds)}}$ .

Remember to watch your units.

Answer:

Time is $562.5$ seconds. To convert to minutes divide by $60$ seconds because there are $60$ seconds in a minute.
So the final answer is $9.375$ minutes
