Leo is running in a 5-kilometer race along a straight path. if he is at the midpoint of the path, how many kilometers does he have left to run?

Let us assume Leo starts from a point (0,0)

Since the total length of the race is 5 km, he will be at (5,0) at the end of the race.

It is given that, he is at the mid point of the race.

Mid point formula is  :

Present coordinate :

He still needs to run 5-2.5 = 2.5 km

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
