Riya and George start walking towards each other from their houses at the speeds of 6 km/h and 8 km/h, respectively. After how long will they meet if the distance between their houses is 28 km.

2 h

Relative speed of Riya and George  = ( 6 + 8 ) = 14 km/h

Distance b/w them = 28 km

Time taken to meet = \(\frac{Distance}{Speed}\)

= \(\frac{28}{14}\)

= 2 hours

So , they will meet after 2 hours
