initial velocity = 10 m/s
final velocity = 0 m/s
distance covered = 10 m
acceleration of the bike, 
2as = v^2-u^2
2(a)(10) = (0)^2-(10)^2
20 a = -100
a = -100/20
a = -5 m/s^2

therefore in the next condition,
initial velocity = 40 m/s
final velocity = 0 m/s
acceleration = -5 m/s^2 ( as mentioned in the question above )
therefore distance traveled by the bike,
2as = v^2-u^2
2(-5)(s) = (0)^2-(40)^2
-10 s = -1600
s = -1600/-10
s = 160 m.
 i hope that  this will help u.
