You are driving a car in London and see that it says that you are going 50.45 km/hr (kilometers per hour). Using the correct amount of significant figures, how fast are you going in feet per minute (ft/min)? (Show work) Is your answer something that is counted or something that is measured? What does that mean? The speed of light is 3.0 * 108 m/s. Convert this measurement to miles per hour.

Final answer:

To convert the speed from kilometers per hour (km/hr) to feet per minute (ft/min), multiply by the appropriate conversion factors. The answer is something that is measured. To convert the speed of light from meters per second (m/s) to miles per hour (mi/h), use the appropriate conversion factors.

Step-by-step explanation:

To convert the speed from kilometers per hour (km/hr) to feet per minute (ft/min), we need to use the conversion factors:

1 km = 3281 ft (since 1 km = 1000 m and 1 m = 3.281 ft)

1 hr = 60 min

First, let's convert the speed from km/hr to ft/hr:

50.45 km/hr * 3281 ft/1 km = 165467.45 ft/hr

Next, let's convert from ft/hr to ft/min:

165467.45 ft/hr * 1 hr/60 min = 2757.79 ft/min

Therefore, you are traveling at a speed of approximately 2757.79 ft/min.

The answer is something that is measured. When we say that something is measured, it means that it is described using a measurement or a numerical value based on observation or calculation.



To convert the speed of light from meters per second (m/s) to miles per hour (mi/h), we need to use the conversion factors:

1 mi = 5280 ft (since 1 mile = 5280 feet)

1 hr = 3600 s (since 1 hour = 3600 seconds)

First, let's convert the speed of light from m/s to ft/hr:

3.0 * 10^8 m/s * 3.281 ft/1 m * 3600 s/1 hr = 6.71 * 10^8 ft/hr

Next, let's convert from ft/hr to mi/hr:

6.71 * 10^8 ft/hr * 1 mi/5280 ft = 1.27 * 10^5 mi/hr

Therefore, the speed of light is approximately 1.27 * 10^5 mi/hr.
