Answer:
5.91 seconds
Step-by-step explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Distance = Speed × Time
⇒Distance = 3.1t
Distance traveled by bicycle that passes through = 3.1t

They both travel the same distance


Hence, time taken by the bicyclist to catch the other bicyclist is 5.91 seconds
