Answer:
Step-by-step explanation:
Let the distance be d
<u>Then the time in travel is</u>
- d/60 one way, d/50 on return
<u>The round trip would take 1/2 hours longer if the average speed was 55 mph</u>
- d/60 + d/50 = 2d/55 + 1/2
- d/60 + d/50 - 2d/55 = 1/2
LCM(60,50,55) = 11*12*5*5 = 3300
- 55d/3300 + 66d/3300 - 120d/3300 = 1/2
- d/3300= 1/2
- d = 1650 miles
