Erica drove from Sarnia at 80km/h. Aisha left Sarnia one hour later and drove along the same road at 100km/h. How far from Sarnia did Aisha overtake Erica?

After one hour, Erica is 80 km away.
Now, Aisha is going to approach erica at 20 km/h (100-80)
so d=80, s=20
t=d/s = 80/ 20 = 4 hours
so after 4 hours, at 100km/h , the distance is 100 x 4 = 400km
hope this helped

Distance = rate X time
Erica's distance = 80t
Aisha's distance = 100(t - 1)
Taisha will overtake Erica shortly after having gone the same distance as Erica.
80(t) = 100 (t -1)
80t = 100t - 100
-20t = - 100
t= 5 hrs after erica left and 5*80 = 400km from Sania.
Erica's distance = 80t
Aisha's distance = 100(t - 1)
Taisha will overtake Erica shortly after having gone the same distance as Erica.
80(t) = 100 (t -1)
80t = 100t - 100
-20t = - 100
t= 5 hrs after erica left and 5*80 = 400km from Sania.
