The amount of time saved on the 86.0 mile trip from Tulsa entrance to Oklahoma City is 0.42 hours

What is time?

Time is the measurement of a past, present, or future event. The S.I unit of time is seconds (s)

To get the time that was saved on the 8.6-mile trip, we use the formula below.

Formula:

  • Ts = (d/v₁)-(d/v₂)................. Equation 1.

Where:

  • Ts = Time saved on the trip
  • d = distance covered during the trip
  • v₁ = Initial legal speed limit
  • v₂ = final/current legal speed limit.

From the question,

Given:

  • d = 86.0 mile
  • v₁ = 55.0 mi/h
  • v₂ = 75.0 mi/h

Substitute these values into equation 1

  • Ts = (86/55)-(86/75)
  • Ts = 1.564-1.147
  • Ts = 0.42 h.

Hence, The amount of time saved on the 86.0 mile trip from Tulsa entrance to Oklahoma City is 0.42 hours.
