Question

Which of the following is the slowest speed?

OPTIONS.....


A= 45km/hr B=10m/s
C=0.9km/hr D=all are equal ​

Answer 1

Answer:

Okay, first let's use some logic here. We know that Option A and Option D are incorrect, because 45km/hr is obviously a greater speed than all of them.

Now, with options B and C in our hand, let's convert km/hr to m/s, I.e,

0.9 km/hr × 5/18

= 9/10 × 5/18

= 1/4

= 0.25 m/s

So, now it's clear that Option C is lesser than Option B, I.e, 10 m/s.

---0.25m/s < 10m/s

---Option C < Option B

Therefore, Option C, 0.9 km/hr is your answer!

I hope it's clear!
