Eduardo’s average speed on his commute to work was 55 miles per hour. On the way home, he hit traffic and only averaged 40 miles
alekssr [168]

Answer:

40(1.25-t)

Step-by-step explanation:

There are 3 components to consider; time, speed and distance

Time and Speed are given.

The distance has to be calculated.

  • Speed to work = 55 miles per hour
  • Time to work = 1.25-T
  • Speed to home = 40 miles per hour
  • Time to home = 1.25-t
  • Total Time = T + t = 1.25

<u>Distance for trip to home</u>

Speed = Distance/Time

40 = Total Distance/1.25-t

Total Distance = 40(1.25-t)

<em>Therefore, 40(1.25-t) is the correct answer.</em>
