Yes it is good luck too you
This means 5 meters/20 steps = x/1,000 steps. 20 times 50 is 1,000, so 5 times 50 is 250 meters. 5/20 can be also reduced to 1/4 = x/1000. Use cross products rule to get 4x = 1,000. Divided both sides by 4 to get x = 250 meters.
M[n(x)] = 4(x - 10) - 11 = 4x - 40 - 11 = 4x - 55
