Answer:The speed of car will be 35km/h and 25 km/h
Step-by-step explanation:
Let the speed of car A be v
Let the speed of car B be u
1h 40min=5/3h
If they both move in same direction then
(v+u)*5/3=100
v+u=60. .......eq-1
If they move in opp. direction
Then (v-u)*10=100
v-u=10. ........eq-2
From eq-1 and eq-2
v+u=60
v-u=10
Then 2v=70 v=35
u=25
The value of speed would be interchange if carB move toward carA
