An airplane is travelling across the country on a 3250 km journey that takes 5 hours to complete. For the first 400 km of the trip, the plane travels at 266.67 Then, the plane travels at 346.15 for 3.25 hours. The final leg of the
journey is completed at an unknown speed.
a. What speed does the airplane travel during the final portion of the trip, in km/h?

b. What was the average speed of the airplane for the whole trip, in km/h?

overcharge is the right answer system

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
