You are leaving for a party at your cousin’s house in a city that is 150 km away. You will travel at an average rate of 50 km/hr. How long will it take you to arrive?

To answer this question, simply divide the total distance by the average rate of 50 km and you should be left with hours if you use dimensional analysis.

×

= 3 hours
