a. 75m
b. 50 m
c. 25m
d. 100m

100m

Explanation:

The distance talks about how far ted has swam. Distance doesn't specify direction like displacement.

The total distance covered by ted will be addition of the dist covered due east and distance covered due west i.e 25m + 75m = 100m

Therefore he swam a distance of 100m
