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:
distance covered by train=20 km
Step-by-step explanation:
let the distance covered by train =x km
then distance covered by bus=. 2x km
total distance 10+x+2x=70
10+3x=70
3x=70-10
x= 60÷3
x=20 km
Step-by-step explanation:
Given :-
A man walks 10 km, then travels a certain distance by train and then by bus as far as twice by the train. The whole journey is of 70km
To find :-
How far did he travel by train ?
Solution :-
The distance covered by a man by walk = 10 km
Let the distance travelled by train be X km
Then,
The distance travelled by bus
=> Twice the distance travelled by train
=> 2X km
Total distance travelled by the man
=> 10 km + X km + 2X km
=> (3X+10) km
According to the given problem
The whole journey = 70 km
=> 3X+10 = 70
=> 3X = 70-10
=> 3X = 60
=> X = 60/3
=> X = 20 km
Therefore, X = 20 km
Answer:-
The distance travelled by the man by the train is 20 km
Check :-
The distance travelled by walk = 10 km
The distance travelled by train = 20 km
The distance travelled by bus = 2×20 = 40 km
Total journey = 10+20+40 = 70 km
Verified the given relations in the given problem.
