please mam mera rpf ka exam h to uski Dani subject ki classes chalana plz
Sir, in the 1st question where we have speed in the ratio 3:4 and a has time 30 minutes more than b so sir 3/4=t/t+30 which makes 3t+90=4t, so t =90

yup I had the same doubt as I solved with both methods I took T(A)= T(B)+30 S(A)*(T(B)+30)=S(B)*T(B) 3T(B)+90=4T(B) Therefore T(B)= 90 mins And ratio approach like u

A car after travelling 18km from a point A developed some problem in the engine and speed become 4/5 of its original speed.As a result,the car reached point B 45 mins late.If the engine had developed the same problem after travelling 30 km from A,then it would be reached B only 36 minutes late.what is the original speed of the car ( in km/hr) and what is the distance between the points A and B..how to solve this type of question?
