It will take the first person 140 minutes and the second person 105 minutes.

60/3 = 20 so it takes the first person 20 minutes to mow one lawn so 20 x 7 = 140

75/5 = 15 so it takes the second person 15 minutes to mow one lawn and 15 x 7 = 105

One lawn care worker can mow 3 lawns in 60 minutes, and another worker can mow 5 lawns in 75 minutes. How long will it take them to mow 7 lawns?
