+205 Bob travels in an airplane a distance of 2100 km. For one-third of the distance, the
airplane flies at a speed of 760 km/h, and for the rest of the distance, it flies at a speed of
800 km/h. How long does the trip take?
+37153 1/3 of the distance = 700 km remaining distance = 1400 km
distance / rate = time
700 km / 760 km/h + 1400 km / 800 km/ hr = ......... hr
