Below is an instruction that describes a task. Write a response that appropriately completes the request in Chinese. Please answer in Chinese.

### Instruction:
 Rajesh walked 10 kilometers less than 4 times the distance that Hiro walked. Together they walked 25 kilometers. How many kilometers did Rajesh walk?


### Response:
 设 H = Hiro走的距离
4H - 10 = Rajesh走的距离
H + 4H - 10 = 25
5H - 10 = 25
5H = 35
Hiro走了7公里，所以Rajesh走了4(7) - 10 = <<7*4-10=18>>18公里
Rajesh走了<<18=18>>18公里。
