Question

Cars A and B start moving with velocities 30 kmph and
20 kmph in opposite directions are separated by 300
km. They will meet each other after a time of
1) 2 hrs 2) 6 hrs
3) 4 hrs
4)8 hrs​

Answer 1

Answer:

6 hrs

Explanation:

Let they meet after a time of t hrs.

Distance covered by A in t hrs= 30t Km

Distance covered by B in t hrs= 20t Km

Total distance is 300Km, hence

$30t + 20t = 300$

$50t = 300$

$t = 6 \: hrs$

Answer:

your correct answer is 6 hours
