Question

anonymous · Answer

Distance = time*speed

Gigi Time = 60
Madel Time = 15

Gigi Speed = x
Madel speed = 2x

Gigi Distance = time*speed = 60*x = 60x
Madel Distance = time*speed = 15*2x = 30x

60x + 30x = 9

90x = 9

x = 1/10

Gigi Distance = 60*1/10 = 6km
Madel Distance = 15*2*1/10 = 3km
