Answer :

Answer: Option A

138 kPa

Step-by-step explanation:

By definition 1 psi (Pound per square inch) is equal to 6.895 Kpa (kilopascals).

So we use this relationship as a conversion factor:

[tex]\frac{6.895\ kPa}{1\ psi}[/tex]

So to know how many kPa represent 20 psi we must multiply 20 psi by the conversion factor

[tex]20\ psi\ *\ \frac{6.895\ kPa}{1\ psi}=137.895\ kPa[/tex]

If we round to the nearest integer we get: 137.895 kPa ≈ 138 kPa

The answer is the option A
