A horse covers a certain distance in 40 minutes if it runs at a speed of 60 km/hr. At what speed the horse can cover the same distance in 30 minutes?

80 Km/hr

Distance covered by horse in 40 minutes - \(\frac{ 60}{60 }\) x 40 = 40 km

Speed at which the horse can cover the same distance in 30 minutes:

Speed = \(\frac{Distance }{Time }\)

Speed = \(\frac{40 }{1/2 }\) = 80 km/hr
