Question

Motion Problem: At 4:00 Gigi and Madel left the music house. Gigi walked east and reached her house at 5:00. Madel rode her bike west and reached her house at 4:15. Madel traveled twice as fast as Gigi. Their houses are 9km apart. How far didi each travel?

Answer 1

Gigi travelled 6km, Madel travelled 3km.

Answer 2

thanks, will you help me in representing? pls?

Answer 3

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

Answer 4

let gigi travel x distance, and madel y distance.. since east and west are opposite.. x+y=9

Next.. gigi takes 1 hours to travel x , and madel 15 mins to travel y

Next.. Sgigig = x/1 and Smadel = y/15 and Smadel = 2*Sgigi

Answer 5
