Question

Time taken to travel (in hours) by six vehicles on two different days

Distance covered (in kilometres) by six vehicles on each day
$\begin{array}{ccc}Vehicle& Day1& Day2\\ A& 832& 864\\ B& 516& 774\\ C& 693& 810\\ D& 552& 765\\ E& 935& 546\\ F& 703& 636\end{array}$
What is the ratio of speeds of vehicle D and Vehicle E on day 2?

• A. 14 : 15
• B. 17 : 13
• C. 15 : 16
• D. 13 : 17
• E. 17 : 15

Answer 1

The correct option is B 17 : 13

Speed of vehicle D on day 2 = 52 kmph
Speed of vehicle E on day 2 = 39 kmph
Ratio = [Speed of vehicle D on day 2 / Speed of vehicle E on day 2] $=\frac{51}{39}=17:13$
