Budhan covers a distance of $19$ km in $2$ hours by cycling one fourth of the time and walking the rest. The next day he cycles (at the same speed as before) for half the time and walks the rest (at the same speed as before) and covers $26$ km in $2$ hours. The speed in km/h at which Budhan walk is
Let us suppose speed of cycling is a km/h and walking is b km/h.
19 = 0.5a + 1.5 b
26 = a + b
on solving these two equation we get,
so answer is option D.
Distance=speed * Time
Let cycle speed is X and walking speed is Y
