A car from a to B, 3 hours travel distance and the whole ratio is 1:3, if another 45 kilometers, just to reach the midpoint of a and B, a and B how many kilometers apart?
12 − 13 = 16, 45 △ 16 = 270 km. A: the distance between a and B is 270 km
The ratio of the first day's journey to the whole journey is 1:4. If you travel another 10 kilometers, you'll get one third of the whole journey
How many kilometers are there between a and B?
On the first day of the trip, 1 / 4 = 1 / 4 of the whole journey
The distance between a and B is 10 (1 / 3-1 / 4) = 120 (km)
