Answer:
X = 180km.
Step-by-step explanation:
Lets say the total journey is 'x' km
2x/5 + x/3 + x/4 + 3 = x ....Equation 1
to get rid of the fractions lets multiply with the least common multiple of the denominators 3, 4 & 5 ....thats 60
Multiply Equation 1 with 15
24x + 20x + 15x + 180 = 60x
59x + 180 = 60x
x = 180 km
