Answer 1

Answer:

Also,

x+y

100

=1

=>100=x+y

=>x+y=100....(ii)

By substitution method,

Substituting equation (i) in equation (ii), we get,

x+y=100

=>y+20+y=100

=>2y=80

=>y=40

Substituting y=40 in equation (i), we get,

x=y+20

=>x=40+20

=>x=60

Thus, speed of car starting from A=x=60 km/hr and speed of car starting from B=y=40 km/hr.
