360 ​ mph ​
600 ​ mph ​

Answer 1

open and see it is the answer

Answer 2

360 mph option (c)

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

=
`(240)/(60)`

=4 hour

Speed of the plane =
`(Total Distance)/(Total Time)`

Speed of the plane =
`(1440)/(4)`

=360 kmph

Hence , the correct answer is 360 kmph
