Answer:
Step-by-step explanation:
Remember - time = distance/speed
distance covered by walk = x/3
distance covered by scooter = (25-x)/24
x/3 + (25-x)/24 = 5/2
= denominator = 24
so - 8x-x+25/24 = 5/2
- take 24 to other side
so 8x - x + 25 = 120/2
7x = 60-25
7x = 35
x =5
distance traveled by walking = 5km
