HELP WITH GRADE 10 MATH

[From: ] [author: ] [Date: 12-02-22] [Hit: ]
Erica is 80 km away.Now,so d=80,so after 4 hours, at 100km/h ,Taisha will overtake Erica shortly after having gone the same distance as Erica.......
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?

EXPLAIN + THANK YOU IN ADVANCE <3

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.
