Question

Convert the following (to the appropriate number of significant figures):

2.953 km / 53.9 m = _____________ (the answer has no units)

Answer 1

To convert km to m and find the answer with the appropriate number of significant figures, convert kilometers to meters and then divide by meters. The answer with the appropriate number of significant figures is 54.80.

Step-by-step explanation:

To convert the units and find the answer with the appropriate number of significant figures, we need to convert kilometers to meters and then divide by meters.

Conversion:

2.953 km = 2.953 x 1000 m = 2953 m (to three significant figures)

Now, divide:

2953 m / 53.9 m = 54.80 (to two significant figures)

Therefore, the answer with the appropriate number of significant figures is 54.80.
