A man walks 10 km, then travels a certain distance by train and then by bus as far as twice by the train. If the whole journey is of 70km, how far did he travel by train?
Answers
Answer:
20 km
Step-by-step explanation:
Let the distance travelled by train be 'x', distance travelled by bus be '2x'
and man walked 10km.
Total distance of the whole journey = 70km
According to the question,
x + 2x + 10 = 70
3x = 70 - 10
3x = 60
x = 60/3
x = 20
Hence the distance travelled by train = 20km
Given :
A man walks 10 km, then travels a certain distance by train and then by bus as far as twice by the train.
To Find :
If the whole journey is of 70km, how far did he travel by train?
Solution:
Distance traveled by man initially = 10 km
Let x be the distance traveled by train = x
We are given that man traveled as far as twice by the train.
Distance traveled by train = 2x
Distance of whole journey = 70 km
So, 10+x+2x=70
10+3x=70
3x=60
x=20
Distance traveled by train = 2x=2(20)=40 km
Hence He traveled 40 km by train
