Answer:

48 minutes.

Step-by-step explanation:

Number of dishes rinsed by Juan in 1 minute

= 480/80

= 6

Number of dishes rinsed by Kevin in 1 minute

= 480/120

= 4

Number of dishes rinsed by Juan and Kevin in 1 minute

= 6 + 4

= 10

Hence, time taken by Juan and Kevin to rinse the dishes

= 480/10

= 48 minutes.

Hence It will take 48 minutes for them to rinse the dishes.
