Answer:

  • a) 12.5 mph,
  • b) 0.36 hours or 21.6 min.

===================

Given

  • Distance = 3.75 miles,
  • Time = 0.3 hours.

a)

  • speed = distance/time
  • s = 3.75/0.3
  • s = 12.5 mph

b)

  • Speed = 12.5 mph,
  • Distance = 4.5 miles.

  • time = distance/speed
  • t = 4.5/12.5
  • t = 0.36 hours
  • t = 0.36*60 min
  • t =  21.6 min
