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

### Instruction:
Mabel lives 4500 steps directly east of Lake High school. Helen lives 3/4 the number of steps that Mabel lives, directly west of the school. What's the total number of steps Mabel will walk to visit Helen so that they can do their assignments together?

### Response:
Mabel lives 4500 steps directly east of Lake High, and since distance=speed*time, to get to Helen's place, Mabel would have to walk for 4500/60= <<4500/60=75>>75 minutes.
Helen lives 3/4 the number of steps that Mabel lives, directly west of the school, meaning she lives 3/4*4500 = <<3/4*4500=3375>>3375 steps directly west of Lake High.
To get to Helen's place, Mabel would have to walk to 4500+3375 = <<4500+3375=7875>>7875 steps.
