Question

A man travelled from the village to the post office at the rate of 25 km/hr and walked back at the rate of 4 km/hr. If the whole journey took 5 gours 48 minutes, find the distance of the post office from the village

Answer 1

Answer:

Total Speed =25+4=29km/h

Total Time=5.8 Hours

Speed=Distance/Time

Distance=Speed×Time

Distance=29×5.8

Total Distance=168.2 km

Distance of the post office from the village=168.2/2=84.1km

Answer 2

Answer:

let the distance be x

then the total distance =2x

Step-by-step explanation:

total speed= 25km/hr and 4km/hr=28km/h

total time taken= 5h 48min.

= 25+4/5 h

= 29/5 h

distance = speed × time

2x=29×29/5 km

2x = 168.2 km

x=1682/2×10 km

x=1682/20 km

x=84.1 km

x=84100 m

So the total distance from the post office to the village is =84100m.or 84.1km.
