Answer 2

Answer:

360 mph option (c)

Step-by-step explanation

To find the total distance add all the distance  i.e,

Total distance = 60+180+540+660

=1440 km

similarly, total time taken =10+3+90+110

=240 minute

To convert 240 minute into hour , divide 240 minute by 60

=$\frac{240}{60}$

=4 hour

Speed of the plane =$\frac{Total Distance}{Total Time}$

Speed of the plane =$\frac{1440}{4}$

=360 kmph

Hence , the correct answer is 360 kmph
