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 per hour. If the round trip took him 1.25 hours, which expression represents the distance, in miles, for his trip home that is missing from the table?t – 1.251.25 – t40(1.25 – t)40(t – 1.25)
Accepted Solution
A:
Answer:40(1.25-t)Step-by-step explanation:There are 3 components to consider; time, speed and distanceTime and Speed are given. The distance has to be calculated.Speed to work = 55 miles per hourTime to work = 1.25-TSpeed to home = 40 miles per hourTime to home = 1.25-t Total Time = T + t = 1.25Distance for trip to homeSpeed = Distance/Time40 = Total Distance/1.25-tTotal Distance = 40(1.25-t)Therefore, 40(1.25-t) is the correct answer.!!
