Question

a man travelled three fourth of his journey by bus One fifth by taxi and remaining 5 km on foot find the total distance of his journey

Answer 1

let the distance of total journey new x
therefore,
3x/4 + x/5 + 5 = 1

(15x + 4x) /20 +5 = 1

19x/20 + 5 = 1

5 = x/20

x = 100 Km. ANSWER.
thanks....

Answer 2

Step-by-step explanation:

Boy cover distance in 2 1/2 hours

he covers by foot = 5km/hr

In 1 hour he complete 5km

he covers distance by bicycle = 10km /hr

In 1 hour he complete = 10 km

total he cover distance 20 km

x/5 + (20-x ) /10 = 5/2

x +20 =25

x = 25-20

x = 5

Hence, the distance covered by foot is 5 km
