Question

The maxium speed of a train is 90 km/hr. it takes 10 hours to cover a distance of 500 km. find the ratio of its average maxium speed

Answer 1

EXPLANATION.

• GIVEN

maximum speed of a train is = 90 km/hr

it takes 10 hours to cover a distance of = 500 km

find the ratio of its average maximum speed.

according to the question,

maximum speed = 90 km/hr

time = 10 hours

distance = 500 km

$\bigstar\bold{\boxed{\green{average \: \: speed \: = \frac{total \: \: distance}{total \: \: \: time}}}}$

average speed = 500 / 10

average speed = 50 km/hr

ratio of maximum speed and average speed =

90 / 50 = 9/5

Therefore,

ratio of maximum speed and average speed =

9:5
