Answer:
4hrs 25mins
Step-by-step explanation:
flew by plane = 1000km
speed = 800km/hr
travelled by train = 250km
time =5/2 hrs
travelled by car = 1200-1150=50km
speed= 75km/hr
total time =?
time = distance / speed
time by plane =1000/800 = 5/4 hrs
time by train = 5/2hrs
time by car = 2/3 hrs
total time = 5/4+5/2+2/3=53/12=4hrs 25 min
