This is 20 points ill give you half the answer and when you make this question again for 20 points ill get 40 points and in that same question ill answer the other half.
M = miles
K = 300/2
S = 240 m
S=K + 30x
240=150+30x
Do this math its easy
3= x
Figure out what x means and do what I said in the begging and ill give you the answer I need the points
