The equation which relates speed, V and time, t to the total distance traveled is 70 = Vt

  • 70 = Vt
  • v(5) = 14
  • V(7) = 10
  • V(3.5) = 20

Since he is traveling at a constant speed, the relationship between, V and t can be written thus :

  • Distance = speed × time
  • 70 = Vt

At time, t = 5

  • 70 = 5V
  • V = 70/5 = 14

At time, t = 7

  • 70 = 7v
  • V = 70/7 = 10

At time, t = 3.5

  • 70 = 3.5v
  • v = 70/3.5 = 20

Therefore, the relationship between V and t with distance is 70 = Vt
