A Person X Started At 3 Hours Earlier At 40km/h From A Place P, Then Another Person Y Followed Him At 60km/h. Started His Journey At 3 O'clock, Afternoon. What Is The Diference In Time When X Was30 Km Ahead Of Y And When Y Was 30 Km Ahead Of X?

Answer»

Time ( when X was 30 km ahead of Y) = (120-30)/20 =4.5h

Time ( when Y was 30 km ahead of X) = (120+30)/20 = 7.5 h

THUS, REQUIRED DIFFERENCE in time = 3H.

Time ( when X was 30 km ahead of Y) = (120-30)/20 =4.5h

Time ( when Y was 30 km ahead of X) = (120+30)/20 = 7.5 h

Thus, required difference in time = 3h.
