If the sun is 150,000,000 km away, how many minutes does it take light to travel from the sun to the earth? Assume light travels at a speed of 3.0x10^10 cm/sec

DrBob222,
distance = rate x time
I would change 150,000,000 from km to cm first, then substitute into the formula and solve for time (in seconds).;
