A Passenger Train Takes Two Hours Less For A Journey Of 300 Km If Its Speed Is Increased By 5 Km/hr From Its Normal Speed. The Normal Speed Is?

Answer»

LET the normal speed be 's' km/hr

Then NEW speed = (s+5) km/hr

300/s−2=300/s+5

On SOLVING this equation we get: 

s = 25 km/hr.

Let the normal speed be 's' km/hr

Then new speed = (s+5) km/hr

300/s−2=300/s+5

On solving this equation we get: 

s = 25 km/hr.
