Xiaofei takes the train to a certain station at the same time every weekend, and then takes the special train at 2:00 pm to the sports school for training. One day, the train arrived at the station 55 minutes earlier. Xiao Fei walked to the sports school on foot. On the way, he met a special car, so he took another car and arrived at the sports school 10 minutes earlier than usual. Ask: How many times is the speed of the car faster than Xiao Fei's walking speed?
