Erik biked north at a constant velocity for a total of 9 minutes. In one-third of that time, he moved 990 meters. What was Erik's velocity? Write your answer as a whole number. meters per minute to the north

To find Erik's velocity, we first calculate the time he traveled. He biked for 9 minutes in total, and in one-third of that time, he traveled 990 meters. One-third of 9 minutes is 3 minutes. Now, velocity is defined as the total distance traveled divided by the total time taken. So, if Erik moved 990 meters in 3 minutes, we can determine his velocity by finding out how much he would travel in 9 minutes at the same speed. If he moved 990 meters in 3 minutes, we can scale that up to find how far he would go in 9 minutes: \[ \text{Distance in 9 minutes} = \text{Distance in 3 minutes} \times 3 = 990 \times 3 = 2970 \text{ meters} \] Now, we can calculate the velocity: \[ \text{Velocity} = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{2970 \text{ meters}}{9 \text{ minutes}} = 330 \text{ meters per minute} \] So, Erik's velocity was **330 meters per minute to the north**.
