#"Speed "= 2.03 m/s#

Explanation:

#"Speed "= "distance"/"time to travel that distance"#

Since it makes the point that "half of his record time was spent traveling the length of the pool", we need to calculate "half of his record time".

#"half of his record time" = (49.17 s)/2 = 24.59 s#

#"Speed "= "distance"/"time to travel that distance" = (50 m)/(24.59 s) = 2.03 m/s#

I hope this helps,
