Explanation:

We are not asked what to look for, bot we can as well get the time taken by the bird to cover the distance at that speed.

Given

average speed = 2.4m/s

Distance = 1.3m

From the formula

Speed = Distance/Time

Time = Distance/Speed

Time = 1.3/2.4

Time = 0.542secs

Hence the total time covered by the bird is 0.542secs
