D = 630km , t = 9h
v = d/t
= 630/9
= 70km/h
2/3x = 630
x = 630/0.67
= 940.3 = Whole Journey Distance
2/3x = 9
0.5x = 9
x = 9/0.5 = 18h = Whole Journey Time
V = d/t
= 940.3/18
= 52.2 KM/H
v = d/t
= 630/9
= 70km/h
2/3x = 630
x = 630/0.67
= 940.3 = Whole Journey Distance
2/3x = 9
0.5x = 9
x = 9/0.5 = 18h = Whole Journey Time
V = d/t
= 940.3/18
= 52.2 KM/H
