Given :-

  • Pranav ran 20.3 km more than Branda

  • Pravin ran 38.6 km


\\ \\

To find :

  • No. of kilometers did Brenda run.


\\ \\

Let :

  • No. of kilometers ran by Brenda be x.


\\ \\

Solution:


\\ \\

Equation formed:-


\\ \\

Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.

Therefore:-


\\ \\


\leadsto \sf38.6 = 20.3 + x

Write the equation


\\ \\


\leadsto \sf38.6 - 20.3 =x

When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)


\\ \\


\leadsto \sf x = 38.6 - 20.3

Arrange the equation because x is always represented at left side.


\\ \\


\leadsto \boxed {\pmb{\sf x = 18.3}}\star

After subtracting 38.6 with 20.3 we will get result as 18.3 .


\\ \\


\therefore \red{ \underline{ \pmb{\frak{Distance ~ covered ~by ~Brenda~ is ~equal ~to~18.3~kilometers}}}}
