ATQ, Let the total distance covered is: (z−50)+z+(z+50)=3z The total time taken is the sum of the time for each segment: 
Then, Average Speed Equation: Average Speed= (Total Distance/Total Time) = 50 km/h 
Now, Set Up the Equation: 
Then, solve for 'z' Find a common denominator (600) and combine terms: 
Cross-multiply and solve: 1800z = 1850z - 7500 7500 − 50z = -7500 z = 150
