<human>:  Kameron has 100 kangaroos on his large farm; Bert has 20 kangaroos on his farm. In how many more days will Bert have the same number of kangaroos as Kameron does now if he buys kangaroos at the same rate of 2 new kangaroos per day?
<bot>: How many more kangaroos does Kameron have than Bert? ** If Kameron has 100 kangaroos, he has 100-20= <<100-20=80>>80 more kangaroos than Bert.
How many days will Bert have the same number of kangaroos as Kameron does now? ** Buying 2 kangaroos every day, it will take Bert 80/2=40 days to have the same number of kangaroos as Kameron has now.
