A bus travels at a uniform speed of 54 km/hr. How many meters does it cover in 1 minute?
900 meters
Convert the speed to metres per second by multiplying by \(\frac{5}{18}\): \(54 \times \frac{5}{18} = 15\) m/s.
One minute is 60 seconds, so distance = speed × time = \(15 \times 60 = 900\) metres.
Hence, the bus covers 900 meters in 1 minute.
A train travelling at a speed of 72 km/hr crosses a post in 20 seconds. If it crosses another train travelling at a speed of 54 km/hr in the same direction in 1 minute 45 seconds, then the difference in length between the two trains is
