Boston is 200 mi away from NY. It takes me 1 hour less to drive to Boston when I drive 10 mi faster than my normal rate. What is my normal rate?

can u also solve it as 200/x -1 = 200/x+10? I got 40 mi/hr

How did you get 40 from that?

Do you mean

200/(x - 1) = 200/(x + 10)

cross multiply

200(x + 10) = 200(x - 1)

200x + 2000 = 200x - 200

NO solution to this
