A man traveled one-third of a distance by bus, Two- fifth by Taxi & remaining 28 km on scooter .
How much distance did he traveled
:
Let d = total distance traveled
:
Total = bus + taxi + scooter
d = 1%2F3d + 2%2F5d + 28
Multiply by 15 to get rid of the denominators, results:
15d = 5d + 3(2d) + 15(28)
15d = 5d + 6d + 420
15d = 11d + 420
15d - 11d = 420
4d = 420
d = 420/4
d = 105 km
