Let the speed of car at A be x kmph and the speed of car at B be y kmph when the car travel in same direction Relative Speed is x−y Dist=100km t=5 hours ∴ Dist =S×T 100=(x−y)5 x−y=20⟶(I) when car travel in opp direction Relative Speed is x+y Dist=100km t=1 hours Dist=ST 100=(x+y)1 x+y=100⟶(II) Solving (I) & (II) x−y=20 x+y=100 2x=120 x=60km/h y=40km/h Speed of the car at A =60 km/h Speed of the car at B=40 km/h The difference of speeds is 60−40=20

Aditya Singh 4 years, 2 months ago

The Euclidean Algorithm for finding HCF (A,B) is as follows: If A=0 then HCF (A,B)=B, since the HCF (0,B)=B, and we can stop. If B=0 then HCF (A,B)=A, since the HCF (A,0)=A, and we can stop. Write A in quotient remainder form (A=BQ+R) Find HCF (B,R) using the Euclidean Algorithm since HCF (A,B)=HCF(B,R) Here, HCF of 441 and 567 can be found as follows:- 567=441×1+126 ⇒ 441=126×3+63 ⇒ 126=63×2+0 Since remainder is 0, therefore, H.C.F of (441,567) is =63 Now H.C.F of 63 and 693 is 693=63×11+0 Therefore, H.C.F of (63,693)=63 Thus, H.C.F of (441,567,693)=63.
