Answer 1

Answer:

Whenever any comparison is to be done among given quantities then we must ensure that all the quantities being compared should have same units.

Here,

Speed of A = 20 m / hr Speed of B = 1 m/min

Now we can either convert speed of A into m / min or convert speed of B into m / hr.

Let us convert the speed of B into m / hr,

Speed of B = 1 m/min

We know that 1 min = 1/60 hour

So,

Speed of B = {1/(1/60) } m/hr Speed of B = 1 * 60 m/hr = 60 m / hr

Now,

We can see that 60 > 20 so,

Speed of B > Speed of A
