If I travel 1900 km in 7 hours and I drove at 60km per hour and then flew at 700km per our, how many hours did I fly and how far did I travel by car?
***
let x=time traveled by car
7-x =time traveled by plane
distance=speed*travel time
..
60x+700(7-x)=1900
60x+4900-700x=1900
640x=3000
x=4.6875
7-x=2.3125
time traveled by car≈4.7 hrs
time traveled by plane≈2.3 hrs
