1.  A car is running at a speed of 108 kmph. What distance will it cover in 15 seconds ?
A. 45 metres
B. 55 metres
C. 450 metres
D. Cannot be determined
E. None of these

Answer: Option C

Explanation:

Speed = 108 kmph
          = (108 x 5/18) m/sec
          = 30 m/sec

∴ Distance covered in 15 sec = (30 x 15) m
                                          = 450 metres.
