speed of a tecain
90 km/h. It takes to hours
to cover a distance of 500
km. finel the ratio of its
average speed to maximum speed​

Answer 1

$\huge\sf\red{Answer:}$

Correct question:

⇒ The maximum speed of a train is 90km/h . It takes 10 hours to cover a distance of 500 km.

Find:

⇒ Find the ratio of its average speed to maximum speed?

According to the question:

⇒ A train assumes 10 hour to go a distance of 500 kilometre, So let's assume the time as 10 hour and the distance covered as 500 km.

Using formula:

★ ${\sf{\green{\boxed{\sf{Speed = \dfrac{Distance}{Time}}}}}}$

Calculations:

★ ${\sf{\green{\boxed{\sf{Speed = \dfrac{500 }{10}}}}}}$

⇒ $\sf{50 \: km/hr}$

But 90 km/hr is the trains maximum speed.

So, According to the question let's calculate the ratio of average speed of the train off maximum speed of the train, we get our answer.

⇒ $\sf {50:90}$

⇒ ${\sf{\underline{\boxed{\green{\sf{5:9 }}}}}}$

Therefore, 5:9 is the ratio of its average speed to maximum speed.

Answer 2

Maximum speed of train = 90 km/h

Distance = 500 km

Time = 10 hours

Average Speed = (500/10)km/h = 50 km/h

Ratio between average speed and maximum speed

= 50 : 90

= 50/90

= 5/9

= 5 : 9
