Question 118

Two boat are travelling with speed of 36 km/hr and 54 km/hr respectively towards each other. What is the distance (in metres) between the two boats one second before they collide?

Solution

Relative speed of boats (since they are travelling towards each other = $$36+54=90$$ km/hr

= $$(90\times\frac{5}{18})$$ m/s = $$25$$ m/s

Distance between them one second before they collide = Distance covered in 1 second = 25 m

=> Ans - (C)
