Homework Statement
The velocity of light is 1.86 x 108 mi/hr. The distance of Mercury from the Sun is approximately 5.78 x 107 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 108 mi/hr = 2.99 x 108 km/hr
time = 5.78 x 107 km / 2.99 x 108 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?
