Let at point M both car meet, so AM = 4v............(v is the speed of car P) BM = 4(v + 40)............(v+40 is the speed of car Q As AM + MB = 480, 4v + 4(v + 40) = 480 8v + 160 = 480 8v = 320 v = 40,,,,,,,,,Speed of car P v + 40 = 40 + 40 = 80.......Speed of car Q Let AB = 480 kms and car P starts from A & car Q starts from B.

Let at point M both car meet, so
AM = 4v…………(v is the speed of car P)

BM = 4(v + 40)…………(v+40 is the speed of car Q

As AM + MB = 480,

4v + 4(v + 40) = 480
8v + 160 = 480
8v = 320
v = 40,,,,,,,,,Speed of car P

v + 40 = 40 + 40 = 80…….Speed of car Q
