In 2003, NASA launched the rover Spirit onto the surface of Mars to explore our planetary neighbor. Near the end of January 2010, Mars was 99.33 million km away from Earth. Assume the speed of communication is at the speed of light, which is 300,000,000 m/s. If a researcher on Earth requested information from Spirit about its temperature, how long did the researcher have to wait for a reply after sending the request? Express your answer in the form minutes and seconds.

one-way trip delay:
(99.33*10^6km)/(3*10^5km/s) = 33.11*10 = 333.1 seconds
Now just convert that to minutes & seconds.
