Answer 1

Answer:

125 metres is the required answer

Explanation:

Given:-

• Uniform Speed ,s = 90km/h
• Time taken ,t = 5s

To Find:-

• Distance travelled ,d

Solution:-

According to the Question

we have to calculate the distance covered by the bike .

Conversion of unit

➻ speed = 90×5/18

➻ speed = 5×5

➻ speed = 25m/s

As we know the relationship between speed, distance travelled and time taken .

• distance = speed × time

substitute the value we get

➻ distance covered = 25×5

➻ distance covered = 125m

• Hence the distance covered by the bike is 125 metres.

Answer 2

Question:

• A bike is travelling at a uniform speed of 90 km/h. Calculate the distance cover in 5 second?

Answer:

• Distance travelled by bike is 125 m.

Explanation:

Given that:

• Uniform speed of bike (s) = 90 km/h.
• Time taken (t) = 5 seconds.

To Find:

• Distance travelled by bike in 5 seconds?

Solution:

Firstly let's convert units of speed from km/h to m/s,

⇒ Speed of bike = (90 × 5/18) m/s

After cancelling 90 with 18, we get :

⇒ Speed of bike = (5 × 5) m/s

➡ Speed of bike = $\pmb{\boxed{\frak{\red{25\:m/s}}}}$

Now, using well known formula i.e, formula used to calculate distance :

↦ Distance = Speed × Time

❏ Putting all known values :

↦ Distance = 25 × 5

➦ Distance = $\pmb{\boxed{\frak{\purple{125\:m}}}}$

• Therefore, distance travelled by bike in 5 seconds is 125 meters.

❏ Know More :

• Distance of any object does not depends on direction of it's motion. It is the path travelled by the object.
• For example :: if a bike travels 20 km towards north and turns to travel south for 5 km then distance travelled by bike will be 25 km.
• Distance can't be negative or zero and it is always more than the displacement of the object.
• Distance is a scalar quantity.
• Formula used to calculate distance is :: Distance = Speed × Time.
