Question

Ramchandra cover a distance of 62.5 km in 90 minutes on scooter find his average speed in min and second.

Answer 1

Answer:

The speed of scooter is 11.57m/s

Step-by-step Explanation:

Given : Distance covered = 62.5 km

Time taken = 90 min

To find : speed in ( m/s )

We know that,

1 km ------------- 1000 m

62.5 km ------------ ?

∴ distance covered = 62.5 × 1000 = 62500m ------- (1)

Also,

1 min ---------- 60 second

90 min --------- ?

∴ time taken = 90 × 60 = 5,400 sec -------- (2)

Therefore ,

Speed = Distance covered / Time taken

Substituting the value in above formula we get,

Speed = 62500/5400

= 11.57 m/s

Hence the speed of scooter is 11.57m/s

Answer 2

✰ Given :-

Distance covered = 62.5 km

Time Taken = 90 min

⠀

✰ Find:-

Speed in (m/s) = ?

⠀

✰ Solution:-

We know that,

1 km------------1000m

Distance covered = 62.5 ×1000

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 62500 m. ------------(1)

1 min = 60 sec

90 min = ?

Time Taken = 90 × 60 = 5400 sec-------(2)

⠀

⠀⠀${\underline{\boxed{\sf{ Speed = \frac{distance \: covered}{time \: taken} }}}}$

⠀

$\sf{ speed = \frac{62500}{5400} }$

${\boxed{\sf{ speed = 115.7 \: m {s}^{ - 1} }}}$

⠀

⠀

Hence The speed of the scooter is 115.7 m/s.
