A car from a to B, 9 / 5 hours to complete the whole 1 / 6, at such a speed, to complete half of the whole how many hours? What's the formula

Solution 1: the whole journey can be regarded as 1 (km) car speed is (1 / 6) / (9 / 5) = 5 / 54 (km / h) half of the time required to complete the whole journey: (1 / 2) / (5 / 54) = 54 / 10 = 5.4 (H) solution 2: it is known that the time required to complete 1 / 6 of the whole journey is 9 / 5 hours, then the time required to complete half of the journey is this

At this speed, the car takes () hours to complete the journey,
If there is a formula, I can understand the explanation

Regard the whole process as unit "1"
Then 36% of the whole process is 1x36% = 0.36
Then the velocity is 0.36 △ 3 = 0.12
12 = 25 / 3 hours

It takes two hours for a car to travel 120 kilometers from place a to place B. at such a speed, how many kilometers in five hours

120 / 2 = 60 (km) 60x5 = 300 (km)

A car runs 120 kilometers in 2 hours. At this speed, it takes 5 hours to travel from place a to place B. what is the distance between the two places? Please tell me more

120÷2×5=300km
