A) 5
B) 4
C) 3
D) 1
Correct Answer: B
Solution :
Let the distance between school and his house = x km According to the given condition, \[\frac{x}{5/2}-\frac{x}{3}=\frac{6+10}{60}\] \[\Rightarrow \] \[\frac{2x}{5}-\frac{x}{3}=\frac{16}{60}\] \[\Rightarrow \] \[\frac{6x-5x}{15}=\frac{4}{15}\] \[\Rightarrow \] \[\frac{x}{15}=\frac{4}{15}\] \[\therefore \] \[x=14\,\,\text{km}\]You need to login to perform this action.
