Use dimensional analysis to determine which rate is greater. Tortoise A walks 71.0 feet per hour and tortoise B walks 12 inches per minute. Which tortoise travels faster? Complete the explanation.

Tortoise A: see below

Step-by-step explanation:

Let's convert Tortoise B's rate of speed to feet per hour. To do so, we can use dimensional analysis and our knowledge of conversion rates.

Multiply this rate by 60 minutes per 1 hour.

Multiply this rate by 1 foot per 12 inches.

By canceling out the units, we can see that ft/hr is left. This is our final answer's unit.

Tortoise B travels at a rate of 60 ft per hour, which is less than Tortoise A's speed, 71 ft per hour. Therefore, Tortoise A travels faster.
