A car from a to B, the first hour to complete a quarter of the whole journey, the second hour to complete 30% of the whole journey, at this time, 9 kilometers away from the end, a and B two How many kilometers apart?
The distance is x km
x-x/4-x*30%=9
X = 20 km
It took two days for the car to travel from city a to city B. on the first day, it took more than 3 / 5 of the city's 96 kilometers. On the second day, it took 1 / 3 of the first day. How many kilometers is the distance between city a and city B
The distance between the two cities is x kilometers
3X/5+96+（3X/5+96）×1/3=X
X=640
The distance between the two cities is 640 km
It takes two days for the car to travel from city a to city B. on the first day, it takes three fifths of the whole journey, which is 108 kilometers more. On the second day, it takes one third of the first day. How about the distance between the two places
Let x km be between the two places, and the equation x = (3 / 5x + 108) / 3 + 3 / 5x + 108
X = 720km
A car travels 120 kilometers on the first day. 56 kilometers on the first day is equal to the total distance on the second day. 65 times on the second day is just the distance on the third day. How many kilometers on the third day?
120 × 56 × 65 = 120 × (56 × 65) = 120 × 1 = 120 (km) a: 120 km on the third day
