Tom drives his car at a speed of 40kmph and reaches his destination in 5hrs and John covers the same distance in 8 hours. If speed of Tomis increased by 10kmph and speed of Ram is increased by 15kmph, what would be the difference between the times taken by them to cover the distance? Choose the most appropriate option
A) 2 hour  B) 1 hour  C) 3 hour  D) 4 hour  E) 5 hour
Distance covered by Ravi at a speed of 40 kmph in 5 hours   ð Distance= Speed x Time = 40 x 5= 200 km   Ram covers same distance in 8 hours =&gt; Speed of Rama =   Distance   Time   = 200/8= 
<gadget id="calculator">200/8</gadget>
<output>25</output>
25 kmph.   Ravi speed is increased by 10 kmph=&gt; New speed of Ravi = 40+10= 
<gadget id="calculator">40+10</gadget>
<output>50</output>
50 kmph   Ram speed is increased by 15 kmph=&gt;New speed of Ram = 25+15= 
<gadget id="calculator">25+15</gadget>
<output>40</output>
40 kmph.   Therefore, time taken by Ravi to cover 200 km at 50 kmph= 200/50= 
<gadget id="calculator">200/50</gadget>
<output>4</output>
4 hours   Time taken by Ram to cover 200 km at 40 kmph= 200/40= 
<gadget id="calculator">200/40</gadget>
<output>5</output>
5 hours 1 hour)   Required time difference= 5 hours – 4 hours = 1 hour   1 hour
<result>B</result>
