Question

Study the following graph and table carefully and answer the questions given below:
Time taken to travel (in hours) by six vehicles on two different days

Distance covered (in kilometres) by six vehicles on each day
$\begin{array}{ccc}Vehicle& Day1& Day2\\ A& 832& 864\\ B& 516& 774\\ C& 693& 810\\ D& 552& 765\\ E& 935& 546\\ F& 703& 636\end{array}$

Which of the following vehicles travelled at the same speed on both the days?

• A. Vehicle A
• B. Vehicle C
• C. Vehicle F
• D. Vehicle B
• E. None of these

Answer 1

The correct option is D Vehicle B

Speed of vehicle A on day 1 = 832/16 =52kmph
Speed of vehicle A on day 2 = 864/16 =54kmph
Speed of vehicle B on day 1 = 516/12 =43kmph
Speed of vehicle B on day 2 = 774/18 =43kmph
Speed of vehicle C on day 1 = 693/11 =63kmph
Speed of vehicle C on day 2 = 810/18 =45kmph
Speed of vehicle D on day 1 = 552/12 =46kmph
Speed of vehicle D on day 2 = 765/15 =51kmph
Vehicle B travelled at the same speed of 43 kmph on both the days.
