Question

6. A diver was collecting water samples from a lake. He collected a sample at every 3 m, starting at 5 m below the water surface. The final sample was collected at a depth of 35 m. How many samples did he collect?​

Answer 1

To find the number of samples collected, we need to determine the number of intervals of 3 meters between 5 meters and 35 meters.

The difference between the starting depth (5 meters) and the final depth (35 meters) is 35 - 5 = 30 meters.

Since the diver collected a sample at every 3 meters, we can divide the total depth by the interval length: 30 / 3 = 10.

Therefore, the diver collected 10 samples in total.
