Question

he conversion factor relating miles to meters is 1mile=1610m1mile=1610m. The speed of light is 3.00×108 m/s3.00×108 m/s. How fast is this in miles per hour (miles/hmiles/h)?

Answer 1

Answer:

6.708 × 10⁸ miles/h

Explanation:

Given:

Speed of Light = 3.00 × 10⁸ m/s

1 mile = 1610 m

⇒1 m = 1/1610 mile

also 1 second = 1/3600  hrs

so 3.00 × 10⁸ m/s = (3.00 × 10⁸  ×3600) / 1610  m/h = 6.708 × 10⁸ miles/h

thus 3.00 × 10⁸ m/s = 6.708 × 10⁸ miles/h
