A. 8
B. 9
C. 10
D. 11
E. 22

CareerGeek · Answer

Let the kms Bansi ran = n
--> Sade ran = n + 8

Total = 30
--> n + (n + 8) = 30
--> 2n + 8 = 30
--> 2n = 22
--> n = 11

IMO Option D

Let us assume that Bansi ran b km and Sandi ran s km.
b+s=30
s-b=8
Solving we get
b=11

ScottTargetTestPrep · Answer

We can let n = the number of kilometers Sade ran and create the equation:

n + n - 8 = 30

2n = 38

n = 19

So, Bansi ran 19 - 8 = 11 kilometers,

Answer: D

Maybe too many steps, but I did it this way; I try to use X and Y because my hand writing is terrible.

X = Bansi
Y = Sade
 X + Y = 30

X = Y - 8

(Y - 8) + Y = 30
2Y = 38
Y = 19

30 - 19 = 11, X = 11
