The Formula

  • d = r t
  • r = d / t
  • t = d / r

Setting Up

  • Write what you know, circle what is asked
  • Convert so the time units match the rate

Two-Part Trips

  • Compute each leg separately, then add distances or times
  • Average speed = total distance / total time, not the average of the speeds

Worked

  • 180 miles at 45 mph → t = 180/45 = 4 hours
Key takeaway

d = r × t
