Question: A train travels from City A to City B at a speed of 90 km/h and covers the distance in 4 hours. If the speed had been 100 km/h, the journey would have taken 3 hours 30 minutes. What is the distance between City A and City B?
a) 330 km
b) 360 km
c) 370 km
d) 400 km
Solution:
Let the distance between City A and City B be d km.
Time taken at 90 km/h:
d/90 = 4
d=90×4=360 km
Time taken at 100 km/h:
360⁄100 = 3.6 hours=3 hours 36 minutes
Hence, the distance between City A and City B is 360 km.
