Question

Places A and B are 100 km apart from
each other on a highway. A car starts from
A and another from B at the same time. If
they move in the same direction, they meet
in 10 hours, but if they move towards each
other they meet in 1 hour 40 minutes. Find
the speeds of the cars.​

Answer 1

Answer:

this is the answer of your question the speed of car A is 35 km/h and car B is 25 km/h

Answer 2

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
