Answer:

93.4 g/mL x 20. mL = 1868g.

489.7m / 53.061 s = 9.23 m/s

216.3 m/66.4 s = 3.26 m/s.

Step-by-step explanation:

Let's analyze each case.

93.4 g/mL x 20. mL

Hewe we are multiplying g/ml*ml. So we have the answer is (g*ml/ml) = g.

So

93.4 g/mL x 20. mL = 1868g.

489.7m / 53.061 s

We are dividing a measurement in m by a measurement in s. So the answer is in m/s.

So

489.7m / 53.061 s = 9.23 m/s

216.3 m/66.4 s

Same as above.

We are dividing a measurement in m by a measurement in s. So the answer is in m/s.

So

216.3 m/66.4 s = 3.26 m/s.
