Question 615906
a person drives from town A to Town B at the rate of 40mph and then flies back at the rate of 120mph. if the total traveling time is 11 hours, how far is it in miles from town A to town B?
**
let x=travel time from town A to town B
11-x=travel time on return trip
Distance=travel time*speed
..
40x=120(11-x)
40x=1320-120x
40x+120x=1320
160x=1320
x=8.25 hrs
11-x=2.75 hrs
distance from town A to town B=8.25*40=330 miles
