Question

If a person walks at 14 km/hr instead of 10km/8hr , he would have walked 20km more . The actual travelled by him is

Answer 1

a person walks 14km instead of 10km
14 km his daily walk + he walked about 20km more so, 14+20=34km he walked

Answer 2

Let x be distance travelled by him walking at a speed of 10km/hr.

hence d = st i.e.,x=10*t------------->1

given walks at 14 km/hr instead of 10km/8hr , he would have walked 20km more i.e., (x+10)=14*t------->2

On soving 1 and 2 we get t=5/2 and x=25 i.e., actual travelled distance.
