Question

Two persons start moving from two points A and B in opposite direction towards each other. One person starts moving from A at the speed of 4 km/ h and meet the other person coming from B after 6 hours . if the distance between a and B is 42 km ,find the speed of other person

Answer 1

Answer:

3km/hr

Step-by-step explanation:

Distance between A and B = 42 km

Speed of one person = 4 km/h

After 6 hours they meet together

Let speed of other person = x km/h

According to the condition,

4×6+x×6=42

24+6x=42

6x=42−24=18

x=3

Speed of other person= 3 km/hr
