I think C because the actual distance travelled by him 70
x+20 =50+20=70
so 70 is correct answer

answer is 50km 14km/h he go x+20
10km/h
he go x 4km/h he covers 20km per hour he go 5km in 10km/h he go 50km

let the actual distance walked is x km.
speed which is maintain to cover x km =10km/hr.
a/q,
new speed =14km/hr.
distance covered =20+x km
now as the man is travelling in same direction equate both the condition by using the formula..
x/10=x+20/14
after solving u will get the answer

For the same interval if the person travelled in 14 kmph so only.

or else you could solve like this

1st hour 10 =14
2nd hour 20 =28
3rd hour 30 =42
4th hour 40 =56
5th hour 50 =70

At speed 10 kmph he reaches 50 km at the same time if he travels in 14 kmph he would reach 70 km. So 70 - 50 = 20. I think u got it.

50 km/hr

we can travel 50 km in 5 hours with the speed of 10 km/hr.
we can travel 70 km in 5 hours with the speed of 14 km/hr.

The difference is 20 km
