Question

a train is running at a speed of 90km/h. how much time will it cross the distance between two station 7.5 km apart.​

Answer 1

Answer:

5 min

Step-by-step explanation:

Let the time be x

Hence,

$\frac{7.5}{x} = 90$

$90x = 7.5$

$x = \frac{7.5}{90}$

$x = \frac{1}{12} hr$

$\frac{1}{12} hr = \frac{1}{12} \times 60$

$\frac{1}{12} hr = 5min$

Hence, time = 5min
