3÷(3+7)= 65438+3/00。
450 kilometers is the total distance.
65438+3-5 of 00 1 = 1 of 00 1
Distance between Party A and Party B
450÷ 10 1 = 4500 km
There is another solution.
Let the distance between the two places be x.
therefore
Driving distance = 1/5X+450
Remaining distance =X- 1/5X+450.
The ratio of the distance traveled to the remaining distance is 3:7.
Distance traveled/remaining distance = 3: 7.
( 1/5X+450)/(X- 1/5X+450)= 3:7
The solution is x=900.
So the distance between the two places is 900*5=4500(km).
A: The distance between the two places is 4500 kilometers.
