Question

If B is inversely proportional to A and B=3.5 when A=2, find the value of B when A =1.4

Answer 1

Answer:

5

Step-by-step explanation:

As B is inversely proportional to A.

so, rekation will be-

B = k/A----------(i) , k is an arbitrary constant

now,

B = 3.5 when A = 2

put it in equation (i)

we have,

3.5 = k/2

so, k = 3.5×2 = 7

put k = 7 in Equation (i) :

B = 7/A ----------(ii)

Now,

Put A = 1.4 in equation (ii)

so,

B = 7/1.4 = 5
