Question

What average speed would be needed for a jet to leave New York at 5:00 and to reach a destination 3000 miles away by 10:00? Put your answer in this form (velocity) : XXX mph

Answer 1

Data:

Initial time = 5:00

Final time = 7:00

Distance = 3000 miles

Required:

Average speed = v ???

Solution:

A/c to newton's law:

v= [ Tf^{2} × (Ti^{2} ]

   ---------------------------        this line mean divided by:

             2 S

Then if we solved it :

we have:

v = 1.8375×10^6 mph
