Q1: Over taking time required for a vehicle with design speed 50 km ph and overtaking acceleration 1.25 m/sec2 to overtake a vehicle moving at a speed 30 km ph, is

A 5.0 secs

B 6.12 secs

C 225.48 secs

D 30 secs

ANS:B - 6.12 secs

T= √(4S/a).
S= 0.7V + 6.
V = 8.33 m/s,
a = 1.25 m/s.
Thus, T=6.15 sec.
