Question

If Mark is travelling
travelling at 54 km/her, how many
meter does he cover
in 32 sec?​

Answer 1

Step-by-step explanation:

Here , speed= 54km/hr

time= 32sec

speed in m/s= 54×1000m/60×60 s

= 540m/36s

=15m/s

therefore distance covered in 32 sec = 15m/s × 32s

= 480m

Answer 2

The distance can be covered in 32 sec is 480 meters.

Given:

Mark is travelling at speed 54 km/hr

To find:

The distance (in meters) can covered by Mark in 32 sec

Solution:

Given that Mark travelling at 54 km per hour

Which means he can travel 54 km in 1 hour

Convert 54 Km into meters  

⇒ 54 km = 54 × 1000 = 54000 meters    [ 1 km = 1000 meters ]

Convert 1 hr into sec ⇒ 1 hr = 60×60 = 3600 sec

                                       [ 1 hr = 60 mins & 1 min = 60sec ]

⇒ Mark can travel 54000 meters in 3600 sec

The distance can be covered in 1 sec =  $\frac{54000}{3600 }$ = 15 meters  

Therefore,

the distance can be covered in 32 sec = 15 × 32 = 480 meters.  

The distance can be covered in 32 sec = 480 meters.
