Step-by-step explanation:
Jerin travels 5 km by foot, 10 km by metro and rest in bus.
Total distance from his house to school is 35km,
so here,
distance which jerin travel by bus is
5km+10km
15 km - 35km
=20km
We have to find the sum of percentages of the distance travelled by walking and by travelling in metro
so,
let the sum of percentages of the distance travelled by walking and by travelling in metro be x
=> 35 of x% = 15
=>35 * x/ 100 = 15
=> 35x/100 = 15
=>35x = 15*100
=> x= 15*100/35
= 300/7
= 42.9%
