Question

A trains travel a distance of 300 km with an average speed of 60km h 1 How much time does it take to cover the distance

Answer 1

Answer :

Distance covered by train = 300km

Speed of train = 60km/h

We have to find time taken by train to cover the distance$.$

★ What is speed of object?

• Speed is defined as the ratio of distance travelled to the time taken.
• It is a scalar quantity having only magnitude.
• It can't be negative or zero.
• SI unit : m/s

Formula : v = d/t

v denotes speed

d denotes distance

t denotes time

By substituting the given values;

→ v = d / t

→ 600 = 300/t

→ t = 300/600

→ t = 1/2

→ t = 0.5 hr

∴ Train will take half hour of time to cover the distance.

Answer 2

Explanation:

Given:

A train travels a total distance 300 km.

It's average speed =60 km/h.

To find:

Total time taken to cover 300 km .

Concept used:

Average speed is total distance covered in total time taken in the journey.

Formula used:

Average speed =total distance/total time taken

Solution:

Total time taken=total distance/average speed

Now putting values given into the formula:

Total time taken= 300/60=5 hrs.

Hence,train tooks 5 hrs to cover 300 km with an average speed of 60 km/h.
