First, you have to convert 45 minutes to hours. Then, you divide 9 to the result of conversion of minutes to hours. That's your final answer. Here's the solution:

[tex] \frac{45}{60} = \frac{3}{4} = 0.75 \\ \frac{9}{0.75} = \frac{900}{75} = 12 \\ 12 km/h [/tex] 
speed=distance/time=(9km/45min)(60min/hr)=12km/hr.
