A) 90 km
B) 180 km
C) 270 km
D) 360 km
Correct Answer: B
Solution :
Let the time taken by car B to reach destination is x hrs. So, the time taken by car A to reach destination is\[(x+2)h\]. Now, \[{{S}_{1}}{{T}_{1}}={{S}_{2}}{{T}_{2}}\Rightarrow 30\times (x+2)=45\times x\] \[\Rightarrow \,\,\,\,\,\,30\,\,x+60=45x\Rightarrow 15x=60\] \[\therefore \,\,\,\,\,\,x=4hrs\] Now, distance between starting point and destination = \[{{S}_{2}}{{T}_{2}}\Rightarrow 45\times 4\]= 180kmYou need to login to perform this action.
