Steve traveled the first 2 hours of his journey at 30 mph and the remaining 3 hours of his journey at 80 mph. What is his average speed for the entire journey?
Answer/Solution
60 mph
Steps/Work
Distance traveled in 2 hours = 2 * 30 = 60 m
Distance traveled in 3 hours = 3 * 80 = 240m
Total distance covered = 240 + 60 = 300m
Total time = 2 + 3 =5 h
Hence avg speed = total distance covered / total time taken
= 300/5 = 60 mph
Answer: A
Distance traveled in 3 hours = 3 * 80 = 240m
Total distance covered = 240 + 60 = 300m
Total time = 2 + 3 =5 h
Hence avg speed = total distance covered / total time taken
= 300/5 = 60 mph
Answer: A
