Jackson and jonah are both swimming. jackson swims at 1350 meters per hour. jonah swims at a speed of 1250 millimeters per second. who swam faster in cm/min? how much faster? a. jackson, 2250 cm/min b. jonah, 7500 cm/min c. jackson, 5250 cm/min d. jonah, 5250 cm/min

For this question we will use the following relations.

100 centimeters=1 meter (or 1 centimeter= 0.01 meter)

10 millimeter=1 centimeter (or 1 mm=0.1 cm)

60 minutes = 1 hour (or 1 min= hour)

Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:

...Equation 1

Likewise, Jonah's swim speed in cm/min can be calculated as:

...Equation 2

As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.

Thus, option B is correct.
