Answer:
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = 
km/min
Time taken up the hill = 
minutes
Speed of Wilmer down the hill = 
km/min
Time taken up the hill = 
minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
Distance up the hill = 
Distance down the hill = 
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
Answer:
(4,4)
Step-by-step explanation:
y = 2x - 4 -------eqn 1
4y = x + 12 ------eqn 2
From eqn 1 y = 2x - 4; insert in eqn 2
4 (2x-4) = x + 12 (open the bracket)
8x - 16 = x + 12 (taking like figures to the same side, sign changes)
8x - x = 12 + 16
7x = 28
x = 28/7
x = 4
From eqn 1
y = 2x - 4
y = 2(4) - 4
y = 8 - 4
y = 4
(x,y) = (4,4)
The difference is 160
c. 200%
