convert km into m by multiplying by 1000:
(7.9 x 10^8 km)(1000m/1km)
divide by the speed of light:
(7.9 x 10^8 km)(1000m/1km)/(3.00 x 108 m/s)=____s
last, divide by 60 to convert to minutes:
(___s)(1 min/60s)
the key to this problem is the UNITS! notice how I eliminate the units I don't want by finding the equivalent units I wanted.
