Answer 1

Answer:

C.12

Step-by-step explanation:

Formula:

(Excluding Stoppages-Including stoppages)/Excluding stoppages

((45-36)/45)*60=12mins

Answer 2

Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Speed without stoppages = 45 km/hr

Speed with stoppage = 36 km/hr

so, difference = $45-36=9\ km/hr$

So, the average stoppage time would be

$\dfrac{Difference}{\text{Speed without stoppage}}\times 60\\\\=\dfrac{9}{45}\times 60\\\\=\dfrac{1}{5}\times 60\\\\=12\ minutes$

Hence, Option 'c' is correct.
