<gadget id="calculator">240/8</gadget>
<output>30</output>
30 kmph   Now, speed of car= (speed of truck + 18) kmph = (30 + 18)= 
<gadget id="calculator">(30 + 18)</gadget>
<output>48</output>
48 kmph   Distance travelled by car= 240 + 0= 
<gadget id="calculator">240 + 0</gadget>
<output>240</output>
240 km   Time taken by car= Distance/Speed = 240/48= 
<gadget id="calculator">240/48</gadget>
