Pick one
A) 26.2 km B) 25.7 km C) 23.2 km D) 26.67 km E) None of these
Explanation:   Distance travelled by each of them is to be made equal.   =&gt; Distance travelled walking = Distance covered cycling.   Let after 4 hours of walking, A walk for x hours more before B catches up with him.   =&gt; Distance = Speed * Time   (4+x)4 = 10x   x = 8/3   Therefore, It takes B 8/3 hours to catch up with A. 26.67 kmistance: 8/3 x 10 = 80/3 km = 26.67   ANSWER: 26.67 km
