The car covered the first part of the journey in 2.8 hours, and the second in 1.2 hours. How much less time was spent on the second part of the journey than on the first? What percentage of the total travel time is spent on the first part of the journey?

Let us find how many times less time the car spent on the second part of the journey than on the first.
According to the condition of the problem, the car covered the first part of the journey in 2.8 hours, and the second part of the journey in 1.2 hours, therefore, the second part of the journey took 2.8 / 1.2 = 2 1/3 times less time than the first part of the journey.
Let’s find how much time was spent on the whole journey:
2.8 + 1.2 = 4 hours.
Consequently, 100 * 2.8 / 4 = 25 * 2.8 = 70% of the total travel time was spent on the first part of the journey.
Answer: 2 1/3 times; 70%.
