Question

help me plls pls pls pls

Answer 1

A car travels at a speed of 72 km / hr

This means that the car travel 72 km in 1 hr

So in 1 hr there is 60 minutes .

Each minute has 60 seconds ... so 60 minutes will have 60×60 seconds

1 hr = 60×60 s = 3600 s

Now 72 km has to be converted to m.

1 km = 1000 m

==> 72 km = 72000 m

So speed in m / s

= 72000 m / 3600 s

= 20 m / s

So the car travels 20 m in 1 s

In 30 seconds it will travel 20 m×30

= 600 m

The answer is 600 m.

Hope it helps you:-)

Answer 2

$\underline{\textbf{Hey Mate Here Is Your Answer}}$

$\underline{\textbf{Given That..}}$

The Car travels at a speed of 72km/hr , And Now We Need To Find What Distance The Car will cover in 30

seconds.

So Now Let's Move For Solution ..

$\underline{\textbf{Solution}}$

Now According To A Car Travels At A speed Of 72km/hr Now We Need To Find The Distance Covered by it In

30sec.

So As We Know That There Are

$\textbf{60 Minutes In 1hr And There Are 60 seconds In 1 Minute }$

So we Have $\Longrightarrow$

$\underline{\mathbf{1 \:Hr \:= \:60min\: \longrightarrow \:60sec\: \times \:60\: = \:3600 seconds}}$

Similarly

$\textbf{In 1km We Have 1000m So We Have }$

$\underline{\textbf{72km = 72000 Metres }}$

So Distance Travelled In One Second = Total Distance / Total Seconds

That Is ..

$\mathbf{\frac{72000}{3600}\: = \:20 \:Metres\: Per\: Second}$

$\therefore{\textbf{In One Second It Will cover A Distance Of 20 Metres }}$

So In 30 Seconds It Will Cover A Distance

$\boxed{\mathbf{Distance = 20m \times 30 = 600m}}$

$\underline{\mathbf{Hence \:The\: Required\: Answer\: Is\: \Longrightarrow}}$

$\boxed{\mathbf{600\: Metres}}$
