The hound chases the fox, the hound moves forward 1.8m with each jump, the fox advances 1.1m with each jump, and the fox jumps exactly 3 times for every 2 jumps of the hound. If the hound is 15m away from the fox at the beginning, how many meters can the hound run to catch up with the fox? ?
猎狗追狐狸，猎狗每跳一次前进1.8m，狐狸每跳一次前进1.1m，猎狗每跳2次的时间狐狸恰好跳3次，如果开始时猎狗距离狐狸15m，那么猎狗跑多少米才能追上狐狸？
