<human>:  Two friends are racing three miles. The first one runs it in 21 minutes. The second one runs it in 24 minutes. If they keep up the same pace, how long combined will it take for them to run 5 miles each?
<bot>: How many minutes does the first one run in? ** The first one runs a mile in 7 minutes because 21 / 3 = <<21/3=7>>7
How many minutes does the second one run in? ** The second runs a mile in 8 minutes because 24 / 3 = <<24/3=8>>8
How many minutes would the first one take to finish 5 miles? ** The first one would finish 5 miles in 35 minutes because 5 x 7 = <<5*7=35>>35
How many minutes would the second one take to finish 5 miles? ** The second one would finish in 40 minutes because 5 x 8 = <<5*8=40>>40
How many minutes will it take in total? ** It will take 75 minutes in total because 35 + 40 = <<35+40=75>>75
