Answer:
<em>Sali's speed was 18.75 km/h.</em>
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As, , so the speed of Jane will be:
Suppose, the speed of Sali is km/h
Sali caught up with Jane when they had both cycled 30 km.
So, <u>the time required for Jane to cycle 30 km</u> and <u>the time required for Sali to cycle 30 km</u>
Given that, Sali started to cycle 4 minutes or after Jane started to cycle. So, the equation will be.......
Thus, the speed of Sali was 18.75 km/h.
In the equation y = 2x + 4, you know that the gradient is 2 (the number before x).
for a perpendicular line you need the negative reciprocal of 2, which is -
.
you then need to use the equation
y -
= m(x - 
)
substitute in your coordinates:
y - -2 = - (x - 3)
simplify:
y + 2 = -0.5x + 1.5
rearrange:
y = -
