When a car goes from city a to city B, it travels 30 kilometers per hour when going and 25 kilometers per hour when returning. What is the speed ratio between going and returning___ At the same time, the distance ratio is___ What is the time ratio between the two cities___ ．

When a car goes from city a to city B, it travels 30 kilometers per hour when going and 25 kilometers per hour when returning. What is the speed ratio between going and returning___ At the same time, the distance ratio is___ What is the time ratio between the two cities___ ．

(1) The speed ratio of going time and returning time: 30:25 = 6:5; (2) because the speed ratio of going time and returning time is 30:25 = 6:5, the distance ratio is 6:5 in the same time; (3) the time ratio of going time and returning time: 130:125 = (130 × 150): (125 × 150) = 5:6; so the answer is: 6:5, 6:5, 5:6

The speed ratio of car a to car B is 3:2. There is a city C between city a and city B. the time for car a and car B to arrive at City C is 5 am and 5 pm respectively. When will car a and car B meet?
If it's OK, add points

If the speed of car a is 3x, the speed of car B is 2x
At 5:00, a arrives at C, and B is 2x * 12 hours away from C (5:00 p.m. minus 5:00 a.m.)
Encounter time = distance △ speed and
That is, (2x * 12) / (2x + 3x) = 24 / 5 = 4.8 hours
4.8 hours after 5:00 is 9.8, so they meet at 9.8, which translates to 9:48 in the morning

A car from a city to B city, 3 hours driving 105 kilometers. With the same speed and 1.2 hours to B city. A city to B city how much
The two related quantities are () ()
(2) The relation between these two quantities is ()
(3) In this relation () must be
(4) The distance traveled is proportional to the time
(5) The car traveled () kilometers

(1) The two related quantities are (distance) (time)
(2) The relationship between these two quantities is (distance = time * speed)
(3) In this relation (velocity) must be
(4) The distance traveled is (positively) proportional to the time
(5) The car traveled (147) kilometers

A car from a city to B city, 3 hours 105 km. With the same speed and 1.2 hours to B city, a city to B city how many kilometers? (solve by proportion)

Suppose that the distance between a and B is x km, 105:3 = x: (3 + 1.2), & nbsp; & nbsp; & nbsp; 3x = 105 × (3 + 1.2), & nbsp; & nbsp; & nbsp; 3x = 441, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 147; a: it is 147 km from a city to B city
