Question

A cyclist covers a distance of 63 km on his bicycle at a certain speed. He finds that the time taken is 2 hours less when he travels at 2 kmh more than his average speed what is time taken by him

Answer 1

Let the original average speed of the cyclist be x km/hr

Time=SpeedDistance

Then as per given condition (x−1)14=x14+31

⇒x(x−1)14x−14(x−1)=31

⇒x2−x14=31

⇒x2−x−42=0

⇒x2−7x+6x−42=0

⇒x(x−7)+6(x−7)=0

⇒(x−7)(x+6)=0

⇒x=7 or −6
