Question

A and B starts to wall at the same time from two places 55 km distance and meet in 5 hours 30 mins; but if A
had halved his pace and B doubled his pace, they would have met in 5 hours. Find their speeds​

Answer 1

Answer:

Step-by-step explanation:

B.6km/h

✔A to B 60km

Let the speed of A= x kmph and that of B = y kmph;

According to the question;

X*6+y*6 = 60

Or, x+y = 10 --------- (i)

And, 

{(2x/3)*5}+(2y*5) = 60

Or, 10x+30y = 180;

Or, x+3y = 18; ---------- (ii)

From equation (i)*3 - (ii)

3x+3y-x-3y = 30-18

Or, 2x = 12

Hence, x = 6 kmph.✔✔✔✔
