The first cyclist bikes 9 miles in 45 minutes.

Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:

  • 60 = 12
  • 45 = X
  • 45 x 12/60 = X
  • 540/60 = X
  • 9 = X

Therefore, the first cyclist bikes 9 miles in 45 minutes.
