We are asked to convert the units of the given value from cm/min to units of meters per hour. The conversion factor needed would be as follows:
100 cm = 1 meter
60 min = 1 hr
19.1×10^8 cm/min ( 1 m / 100 cm ) ( 60 min / hr ) = 1.146×10^9 m/h
Therefore, the correct answer is the second option.
Hope this helps. Have a nice day.
