ACIO Exam Numerical Ability

Sunita and Sumedha start travelling in the same direction at 8 km/hr and 13 km/hr respectively. After 4 hours, Sunita doubled her speed and Sumedha reduced her speed by 1 km/hr and reached the destination together. How long did the entire journey last?

Read Solution (Total 2)

112 Km.

If the total journey is of 'x' Km. and Given initial Speed(in Km/hr) of Sunita=8 and Sumedha=13
So Time taken by Sunita=Time taken by Sumedha
4+ (x-(4*8))/16 = 4 + (x-(13*4))/12
x=112
