Answer:

17:55

Explanation:

What time did the plane leave London City airport?

speed = distance/time

time = distance/speed

time = 256 miles / 192 mph

time = 1.333 hours = 1 1/3 hours = 1 hour 20 minutes

The plane flew for 1 hour and 20 minutes.

19:15 - 1:20 =

(Borrow 1 hour from 19 leaving 18. Convert the borrowed hour to 60 minutes and add to 15 minutes making it 75 minutes.)

= 18:75 - 1:20

= 17:55
