Answer:
42 km
Step-by-step explanation:
1/4x + {(1/2)×(1/4)} + [{3 × 4/ (1/2 × 1/4)}] + 21km = X
1/4 + 1/8 + 3/24 km + 21 = X
6 + 3 + 3/24(add all fraction, their LCM = 24) + 21km = X
12/24 + 21 = X
If 12 parts of 24 = the fractions then the remaining 12 parts = 21km
and 12 parts is the half of 24.
So, 12(21km) + 12(21km) = 42 km
