Answer:
13/25 * 2/3 = 26/75
Multiplying numerators: 13 * 2 = 26
Multiplying denominators: 25 * 3 = 75
Distance=speed times time
if they take the same time, we cal the time , t
b=bike speed
w=walking speed
bikedistnace=17=bt
walkdistance=9=wt
b is 4 more than w
b=4+w
we have
17=bt
9=wt
b=4w
ok so
multiply first equation by 9 and 2nd by 17
153=9bt
153=17wt
set equal
9bt=17wt
divide both sides by t
9b=17w
sub b=4+w for b
9(4+w)=17w
distribute
36+9w=17w
minus 9w both sides
36=8w
divide both sides by 8
4.5=w
he walks 4.5kph
Answer: Undefined
Step-by-step explanation:
Slope=rise/run
For vertical lines, there is no "run" so the bottom of the slope fraction would be 0. Dividing anything by 0 is always undefined.
