Question

Караван верблюдов прошел по пустыне в первый день 42км,а во второй день 60км,причем во второй день караван был в пути на 3 часа больше,чем в первый.Сколько времени караван находился в пути каждый день,если оба дня он передвигался с одинаковой скоростью?

Answer 1

60-42=18
18/3=6км/ч
60/6=10ч в первый день
42/6=7ч - во второй

Answer 2

Calculation of Time Spent by the Caravan Each Day

To calculate the time spent by the caravan each day, we need to consider the distances traveled and the relative speeds.

Let's assume that the caravan traveled at a constant speed on both days.

On the first day, the caravan traveled a distance of 42 km.

On the second day, the caravan traveled a distance of 60 km and was on the road for 3 hours longer than on the first day.

To find the time spent by the caravan each day, we can use the formula:

Time = Distance / Speed

Let's denote the time spent on the first day as T1 and the time spent on the second day as T2.

For the first day: T1 = 42 km / Speed

For the second day: T2 = 60 km / Speed

We know that the caravan traveled at the same speed on both days, so we can set up the following equation:

T2 = T1 + 3 hours

Now, let's solve the equation to find the time spent by the caravan each day.

Substituting the values of T1 and T2 into the equation, we get:

60 km / Speed = 42 km / Speed + 3 hours

Simplifying the equation, we have:

60 km = 42 km + 3 hours * Speed

Subtracting 42 km from both sides of the equation, we get:

18 km = 3 hours * Speed

Dividing both sides of the equation by 3 hours, we find:

Speed = 18 km / 3 hours = 6 km/h

Now that we know the speed of the caravan, we can calculate the time spent each day.

For the first day: T1 = 42 km / 6 km/h = 7 hours

For the second day: T2 = 60 km / 6 km/h = 10 hours

Therefore, the caravan spent 7 hours on the first day and 10 hours on the second day.

Please note that the above calculations assume a constant speed throughout the journey and do not take into account any breaks or rest periods.
