If a tank line uses 5 liters per minute and runs for 40 minutes, how many liters are used?

Explanation:
The main idea is rate multiplied by time gives total quantity. A flow of 5 liters per minute running for 40 minutes means 5 × 40 liters. The units line up as (liters per minute) × (minutes) = liters, so the total is 200 liters. Therefore, 200 liters are used.
