Ruben and Claire are training to run a marathon in the spring. Ruben runs 16 miles over a 4-day period. Claire runs 12 miles over a 3-day period. Are they running at the same rate of speed? Respond "1" for yes or "2" for no.(1 point) .

Answer 1

To determine if Ruben and Claire are running at the same rate of speed, we can calculate their average daily mileage:

• Ruben runs 16 miles over 4 days: \[ \text{Ruben's average} = \frac{16 \text{ miles}}{4 \text{ days}} = 4 \text{ miles per day} \]

• Claire runs 12 miles over 3 days: \[ \text{Claire's average} = \frac{12 \text{ miles}}{3 \text{ days}} = 4 \text{ miles per day} \]

Since both Ruben and Claire run an average of 4 miles per day, they are running at the same rate of speed.

The answer is: 1
