Edwin biked north at a constant velocity for a total of 15minutes. In one-third of that time, he moved 850meters. What was Edwin's velocity?

To solve this problem, we need to find out how far Edwin biked in the total time of 15 minutes.

Step 1: Determine the distance Edwin biked in one-third of the total time. We know that in one-third of the time, which is 15 minutes / 3 = 5 minutes, Edwin biked 850 meters.

Step 2: Calculate the total distance Edwin biked. Since the velocity is constant, we can multiply the distance he biked in one-third of the time by 3 to get the total distance. So, 850 meters * 3 = 2550 meters.

Step 3: Convert the total time from minutes to seconds. We know that 1 minute = 60 seconds. So, 15 minutes = 15 * 60 = 900 seconds.

Step 4: Calculate the velocity. Velocity is defined as the total distance divided by the total time. So, Edwin's velocity = total distance / total time = 2550 meters / 900 seconds = 2.83 meters/second.

So, Edwin's velocity was 2.83 meters/second.
