Question

DIRECT AND INVERSE PROPORTIONS-
A train is moving with uniform speed of 80 km/hr. How far will it travel in 35 minutes?

Answer 1

Distance traveled by train in 1 hour = 80 km

⇒ Distance traveled by train in 60 minutes = 80 km

⇒ Distance traveled by train in 1 minute = $\frac{80}{60}\mathrm{km}$

⇒ Distance traveled by train in 35 minutes =$\frac{80}{60}\times 35\mathrm{km}=46.67\mathrm{km}$
