1. Rehman walks at 8 km/hr and Roma cycles at 13 km/hr towards each other. What was the distance between them when they started if they meet after 36 minutes?

Speed of Rehman = 8 km/hr and speed of Roma = 13 km/hr They are travelling towards each other, thus relative speed = 8 + 13 = 21 km/hr Time taken = 36 min = $$frac{36}{60}$$ hr = $$frac{3}{5}$$ hr Distance = speed $$ imes$$ time = $$21 imes frac{3}{5} = frac{63}{5}$$ = $$12.6$$ km => Ans - (A)
