Question

3.) Light travels at a speed of 1.25 x 107 miles per minute. Pluto's average distance from the

Sun is about 3,550,000,000 miles. On average, how long does it take sunlight to reach Pluto?

Answer 1

I have no idea whether those numbers are correct, and I'm not gonna bother looking them up.

But you gave us a speed and a distance, and you asked for a time.

We can just go ahead and use the formula: Time = (distance) / (speed) .

IF your numbers are true, then

Time = (distance) / (speed)

Time = (3.55 x 10⁹ mi) / (1.25 x 10⁷ mi/min)

Time = (3.55 x 10⁹ / 1.25 x 10⁷) minutes

Time = 2.84 x 10² minutes

Time = 284 minutes

Time = 4 hours 44 minutes
