  1. A train travelling at a speed of 55 km/hr travels from place X to place Y in 4 hours. If its speed is increased by 5 km/hr., then the time of journey is reduced by
    1. 25 minutes
    2. 35 minutes
    3. 20 minutes
    4. 30 minutes
Correct Option: C

Distance between stations X and Y = Speed × Time
= 55 × 4 = 220 km.
New speed = 55 + 5 = 60 kmph

∴   Required time =
220
60

=
11
hours
3

= 3 hours 40 minutes.
∴   Required answer
= 4 hours – 3 hours 40 minutes
= 20 minutes
