Question

Which is greater a speed of 36 kmph or 8m/sec ? What is the difference in the distances travelled in 1 second?​

Answer 1

Answer:

If it helps mark me as brainliest.

Step-by-step explanation:

8m/sec= 28.8 km/hr

So, 36kmph is greater.

In 1 sec, 36kmph covers a distance of 10 m.

In 1 sec, 8m/sec covers a distance of 8m.

Therefore, difference= 10-8 m=2m

Answer 2

Answer:

Step-by-step explanation:

for that you need to convert both the speeds into the same unit

1 km = 1000 m                                      1 h = 60 mins, 1 min = 60 sec

∴ 36 km = 36 * 1000                          ∴1 h = 60*60

              = 36000 m                                  = 3600 sec

36 km/h = 36000 / 3600

              = 10 m/sec

hence as 10m/sec > 8 m/sec

∴ 36 km/h > 8m/sec
