Question

Find distance covered in 2 hours its speed is 4 metre per second

Answer 1

Given:

• Time = 2 hours
• Speed = 4 m/s

What To Find:

We have to find -

• The distance.

Formula Needed:

The formula is -

• Distance = Speed × Time

Solution:

• Converting the time in seconds.

We know that -

⇒ Time = 2 hours

We also know that -

⇒ 1 hour = 60 minutes

⇒ 1 minute = 60 seconds

So it will be,

⇒ 1 hour = 3600 seconds

So -

⇒ 2 hours = 2 × 3600 seconds

⇒ 2 hours = 72000 seconds

• Finding the distance.

We know that -

⇒ Distance = Speed × Time

Substitute the values,

⇒ Distance = 4 m/s × 7200 s

Cancel the s,

⇒ Distance = 4 m × 7200

Multiply the values,

⇒ Distance = 28800 m

Convert the distance in km,

⇒ Distance = 28800 ÷ 1000

Divide the values,

⇒ Distance = 2.88 km

Final Answer:

∴ Thus, the distance is 2.88 km or 28800 m.
