Answer:
- lets classsify this into sections
- we have three sections here air,ship and train
Step-by-step explanation:
air ship train total
distance - 2x x 2400
speed - - - -
time 10 30 10 50
from question we can easily derive this
we know that speed = dis/time
here we have get 48 as total speed
let x be 48 then we can get 480 is distance of train and we all know that ship distance = 2x
ie, 2×480 = 960km
