Question 960799
A man drove at the rate of 50 km/h while outside a city and 30 km/h while within the city. If a trip of 33 km took him 46 minutes, how much of the trip was outside the city?(It is asking about the time)
***
46 min=46/60=23/30 hr
let x=time driving outside the city
46-x=time driving within the city
..
distance=speed*travel time
50x+30((23/30)-x)=33
50x+23-30x=33
20x=10
x=10/20=1/2
how much of the trip was outside the city? 1/2 hr
