Answer 1

HEY BUDDY..!!

HERE'S THE ANSWER..

_____________________

♠️ We know, speed is ratio of distance traveled to the time taken, i.e

✔️ Speed = Distance / time

⏺️speed = 10 m / s

⏺️ distance = 1 km = 1000 m

⏺️time = t = ?

=> Speed = Distance / time

=> time = distance / speed

=> time = 1000 / 10

=> [ time = 100 s ]



HOPE HELPED..

JAI HIND..

Answer 2

1 second = 10m (Given)

10 m = 1 second

-----------------------------------------------------------------------------------------------

STEP 1: Find 1 m:

We divide by 10 on both sides to find 1 m:

1 m = 1 ÷ 10 sec

1m = 1/10 sec

-----------------------------------------------------------------------------------------------

STEP 2: Find 1 km:

Since we know that 1000m = 1km, we multiply the seconds needed by 1000:

1 km = 1/10 x 1000 seconds

1 km = 100 seconds

-----------------------------------------------------------------------------------------------

Answer: The child needs 100 seconds to crawl 1 km.
