<human>:  James and 4 of his friends volunteered to plant flowers. In 2 days, they were able to plant a total of 200 flowers. If each of them planted the same number of flowers, how many flowers did James plant in a day?
<bot>: How many people volunteered to plant flowers? ** There were 1 + 4 = <<1+4=5>>5 of them who volunteered to plant flowers.
How many flowers did the 5 of them plant in a day? ** Each day, the 5 of them planted a total of 200/2 = <<200/2=100>>100 flowers.
How many flowers did James plant in a day? ** Thus, James planted 100/5 = <<100/5=20>>20 flowers in a day.
