remaining 3 km on foot. What is the length of his total journey?​

Answer 1

Answer:

so here is your answer please make ma brainlist

Step-by-step explanation:

Let the length of his total journey be x

So,

52​x+31​x+41​x+3=x

solving

x(52​+31​+41​)−x=−3

=x(52​+31​+41​−1)=−3

=x(602×12+20+1×15−60​)=−3

=x(6024+20+15−60​)=−3

=x(60−1​)=−3

=60x​=3

∴x=180 km
