Answer 2

Answer:

• Let x be the distance travelled by foot and

• Y be the distance travelled by bicycle

Given that

• , the total distance travelled by a man is 50 km in 8 hours , partly on foot and on bicycle

• So, the first equation is x+y=50………..(1)

We know that the formula,

• time =distance/speed

• So , x/5+y/7=8hours

• or 7x+5y=280….(2)

• By solving these two equations we get the distance travelled by man on foot

• Therefore, the distance travelled by a man on foot is 15km
