Fraction equation of mathematics problem in grade two of junior high school In the process of urban renewal, a 2400m long road needs to be renovated. In order to reduce the impact of construction on urban traffic, the actual work efficiency is 20% higher than the original plan. As a result, the task is completed 8 hours ahead of schedule. How many meters per hour is the original plan?
If the original plan is x meters per hour, the actual plan is 1.2x meters per hour
2400/x-2400/1.2x=8
2400/x-2000/x=8
400/x=8
8x=400
x=50
