【Question 13】  
City A and City B are 55 kilometers apart. Xiao Wang starts from City A to City B, first riding a bicycle for 25 kilometers, then switching to a bus, which travels at twice the speed. Upon arriving in City B, he finds that the time spent cycling is 1 hour more than the time spent on the bus. Xiao Wang's cycling speed is $\qquad$ kilometers/hour.
【Analysis and Solution】
City A and City B are 55 kilometers apart, of which 25 kilometers were cycled, and $55-25=30$ kilometers were traveled by car; the speed of the car is twice the speed of cycling;
then in the same time, the distance traveled by car is twice the distance cycled; so traveling 30 kilometers by car, in the same time, cycling would cover $30 \div 2=15$ kilometers; and the time spent cycling is 1 hour more than the time spent traveling by car; cycling 1 hour covered $25-15=10$ kilometers; Student Wang's cycling speed is $10 \div 1=10$ kilometers/hour.
