Q2 Consider the formula that relates distance, velocity, and time (d = vt). If you are interested in the time it takes for a snail traveling at a speed of 2 centimeters per second to crawl up a 1-meter section of a wall, which unit conversion makes the most sense to use?

Question

Converting meters to centimeters by dividing 1 meter by 100 centimeters.
Converting meters to centimeters by multiplying 1 meter by 100.
Converting meters to centimeters by multiplying 1 meter by (1 meter)/(100 centimeters)
Converting meters to centimeters by multiplying 1 meter by (100 centimeters)/(1 meter)

Answer 1

To convert meters to centimeters, you should use the conversion factor where 1 meter = 100 centimeters. Therefore, the most appropriate conversion is:

Converting meters to centimeters by multiplying 1 meter by 100.

This means you would calculate:

1 meter × 100 centimeters/meter = 100 centimeters.

After converting the distance, you can then use the formula \(d = vt\) to find the time \(t\) it takes for the snail to crawl up 100 centimeters at a speed of 2 centimeters per second.
