A truck covers a distance of 360 km at a certain speed in 8 hours. How much time would a car take at an average speed which is 18 kmph more than that of the speed of the truck to cover a distance which is 14 km more than that travelled by the truck ? Choices.
A) 6 hours
B) 5 hours
C) 7 hours
D) 8 hours
E) None
Explanation :   Speed of the truck = Distance/time = 360/8= 
<gadget id="calculator">360/8</gadget>
<output>45</output>
45 kmph   Now, speed of car= (speed of truck + 18) kmph = (45 + 18)= 
<gadget id="calculator">(45 + 18)</gadget>
<output>63</output>
63 kmph   Distance travelled by car= 360 + 81= 
<gadget id="calculator">360 + 81</gadget>
<output>441</output>
441 km   Time taken by car= Distance/Speed = 441/63 = 8 hours.   Answer – 8 hours
