Then find the total time Nissa spends cutting the claws: 16 claws * 10 seconds / claw = 160 seconds. Then find the total time she spends cleaning the cats' ears: 90 seconds / ear * 2 ears = 180 seconds. Then find how long the shampooing takes in seconds: 5 minutes * 60 seconds / minute = 300 seconds. Then add the time she spends on each task to find the total time she spends grooming the cat: 160 seconds + 180 seconds + 300 seconds = 640 seconds. The answer: 640.
