To calculate the rate at which an object moves you subtract Position A, 5.20 m, from Position B, 102.10 m, and then divide by the time it took to move between positions, 4.81 s. Using the rules presented here, what should the final answer be?

a. 20 m/s
b. 20. m/s
c. 20.1 m/s
d. 20.15 m/s

h let me think

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
