Bob earns $2 every 20 minutes. How long will it take Bob to earn $5000?
Answer provided by our tutors
Bob's rate of earning money is: 2/20 = 1/10 = $0.1 per min
To find our how long (in minutes) it takes for Bob to earn $5,000 we divide 5,000 by 0.1:
5,000/0.1 = 50,000 min
50,000/60 = 833 hr 20 min = 34 days 17 hr 20 min
