Question

Light travels at a speed of 1.17 × 107 miles per minute. Pluto's average distance from the Sun is 3,670,000,000 miles. On average, how long does it take sunlight to reach Pluto? Enter your answer in scientific notation, and, if necessary, round your multiplier to the nearest hundredth.

Answer 1

Answer:

It will take 5 hours 8 minute.

Step-by-step explanation:

Speed of light is $1.17\times 10^7$ miles/min

Distance between the Pluto and the Sun is $3,670,000,000=3.6\times 10^9$ miles.

We know that,

$\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}$

i.e $\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}$

Putting the values,

$\text{Time}=\dfrac{3.6\times 10^9}{1.17\times 10^7}=308\ min=5\ hr\ 8\ min$
