Solution

The correct option is A
8 kmph

Let S's speed = x kmph and T's speed is = (14 - x) kmph

$\Rightarrow$ $\frac{48}{x} + \frac{48}{14 - x} = 14$

$\Rightarrow$ x = 8 kmph

The correct option is A 8 kmph Let S's speed = x kmph and T's speed is = (14 - x) kmph ⇒ 48x+4814−x=14 ⇒ x = 8 kmph

The correct option is A
8 kmph

Let S's speed = x kmph and T's speed is = (14 - x) kmph

$\Rightarrow$ $\frac{48}{x} + \frac{48}{14 - x} = 14$

$\Rightarrow$ x = 8 kmph
