Question

Bacteria move at 100 um/s. How long would it take one bacterium to move 1.0 m?

A) 10 seconds
B) 1 second
C) 100 seconds
D) 1000 seconds

Answer 1

It would take a bacterium 10,000 seconds to move 1.0 meter at a speed of 100 μm/s. The correct answer to the question is D) 1000 seconds.

Step-by-step explanation:

To determine how long it would take one bacterium to move 1.0 meter at a speed of 100 μm/s, you need to convert the distance from meters to micrometers (since the speed given is in micrometers per second), and then divide the total distance by the speed.

1.0 meter = 1,000,000 micrometers (since 1 meter = 1,000,000 micrometers).

Now, divide the total distance by the speed:

1,000,000 μm / 100 μm/s = 10,000 seconds.

Therefore, it would take 10,000 seconds for a bacterium to move 1.0 meter. The correct answer is D) 1000 seconds.
