A) 36 min
B) 24 min
C) 32 min
D) 28 min
Correct Answer: C
Solution :
\[\frac{\text{Speed}\,\,\text{of}\,\,\text{car}\,\,x}{\text{Speed}\,\,\text{of}\,\,\text{car}\,\,y}=\frac{5}{6}\] \[\therefore \] Speed of car \[=x=\frac{5}{6}\times 90=75\,\text{km/h}\] Relative speed \[=90+75=165\]km/h Time taken to meet each other \[=\frac{\text{Distance}}{\text{Relative}\,\,\text{speed}}=\frac{88}{165}\] \[=\frac{8}{15}\text{h}=\frac{8}{15}\times 60\,\,\min =32\,\,\min \]You need to login to perform this action.
