A train covers a distance in 1 hr 40 min, if it runs at a speed of 96 Km/hr on an average. Find the speed at which the train must run to reduce the time of journey to 1h 20 min

A) 120 Km/hr
B) 90 Km/hr
C) 144 Km/hr
D) 150 Km/hr

Correct Answer:

A) 120 Km/hr

Description for Correct answer:

Distance = speed X time

\(\Large 96 \times \frac{100}{60} = 160 km\)

New time = \(\Large \frac{80}{60}h = \frac{4}{3}h\)

New speed = \( \Large 160 \times \frac{3}{4} = 4 \times 3\)

=120 Km/hr.
