45.7 s

Step-by-step explanation:

Darya:

Number of laps = 13

Average time per lap = 23.5 seconds

Total time to swim 13 laps = Number of laps × Average time per lap

= 13 × 23.5

= 305.5 seconds

Kana:

Number of laps = 10

Average time per lap = 25.98 seconds

Total time to swim 10 laps = Number of laps × Average time per lap

= 10 × 25.98

= 259.8 seconds

It took longer for Darya to swim

13 laps than for Kana to swim 10 laps.

How much longer?

= 305.5 seconds - 259.8 seconds

= 45.7 seconds
