Answer 1

Step-by-step explanation:

above answer is correct

but scientific notation of 4133.33 km is 4.13333 km

Answer 2

Given - Speed and time

Find - Distance and scientific notation

Solution - The distance covered in scientific notation is 4.13*10³ km.

Time = 3 hours 20 minutes

60 minutes = 1 hour

20 minutes = 1*20/60

20 minutes = 1/3 hour

Time = 3 + 1/3

Time = 10/3 hours

Distance = speed*time

Distance = 1240*10/3

Distance = 12400/3

Distance = 4133.3 km

Scientific notation = 4.13*10³ km

So, the distance covered by airplane is 4.13*10³ km.
