Step-by-step explanation:
Travel by taxi =1/3rd
travel by train = 2/5th
travel by bus = 1/15th
travel on foot = 7200m
Step 1 - FIND THE REMAINING PART OF THE JOURNEY.
1 - 2/5 - 1/3 - 1/15= 0.2 or simply 2/10 = 1/5
remaining journey = 1/5
............................................
Step 2 - FORM AN EQUATION
1/5 of the journey = 7200m
convert it into km = 7200/1000 = 7.2 km
1/5 of the journey = 72/10
total distance = 72/10 *5 /1 = 5
total distance = 72/2 = 36 km
The total distance of the journey is 36 km = answer
