The conversion factor relating miles to meters is 1mile=1610m. the speed of light is 3.00×108 m/s. how fast is this in miles per hour (miles/h)?

This is an example of a unit conversion problem. To solve this, recall the following conversion factors:

1 min = 60 s

1 h = 60 min

The problem also gives the conversion factor for miles to meter:

1 mi =1610 m

To convert the speed of light into the desired unit the following steps must be carried out:

These conversion may be done individually or simultaneously in a single dimensional analysis equation. The equation below shows the simultaneous conversion in one equation:

Since the answer must be expressed with only 3 significant figures, the final answer is:

Keywords: unit conversion, dimensional analysis

answer: 12

step-by-step explanation:

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
