## Homework Statement

The velocity of light is 1.86 x 10

^{8}mi/hr. The distance of Mercury from the Sun is approximately 5.78 x 10

^{7}km. How many

__minutes__will it take for light from the Sun to travel to Mercury?

## Homework Equations

1 mi = 1.609 km

time = distance/speed

60 min/1 hr

## The Attempt at a Solution

1.609 km/1 mi * 1.86 x 10

^{8}mi/hr = 2.99 x 10

^{8}km/hr

time = 5.78 x 10

^{7}km / 2.99 x 10

^{8}km/hr = 1.933 x 10

^{-1}hr

60 min/1 hr * 1.933 x 10

^{-1}hr = 115.98 x 10

^{-1}min

Answer: 11.598 minutes.

That answer does not make sense to me. What did I do wrong here?
