Problem Analysis

We are given that a horse and its foal are returning home from a field along a 10 km road. The horse walks at a speed of 10 km/h, while the foal walks at a speed of 5 km/h. The horse makes stops every 12 minutes at regular intervals, while the foal walks without stopping. We need to determine how many minutes the horse was on the road between two stops.

Solution

To solve this problem, we can calculate the time it takes for the horse to cover the entire distance of 10 km and then subtract the time it spends on stops.

The time it takes for the horse to cover the entire distance of 10 km can be calculated using the formula:

Time = Distance / Speed

For the horse, the time taken to cover 10 km is:

Time taken by horse = 10 km / 10 km/h = 1 hour

Since there are 60 minutes in an hour, the time taken by the horse to cover 10 km is:

Time taken by horse = 1 hour * 60 minutes/hour = 60 minutes

Now, we need to subtract the time the horse spends on stops. We know that the horse makes stops every 12 minutes. To find the number of stops the horse makes, we can divide the total time taken by the horse by the time between stops:

Number of stops = Total time taken by horse / Time between stops

Since the horse makes stops every 12 minutes, the time between stops is 12 minutes. Therefore, the number of stops the horse makes is:

Number of stops = 60 minutes / 12 minutes = 5 stops

Now, we can calculate the time the horse spends on stops by multiplying the number of stops by the time between stops:

Time spent on stops = Number of stops * Time between stops

Substituting the values, we get:

Time spent on stops = 5 stops * 12 minutes/stop = 60 minutes

Finally, we can calculate the time the horse was on the road between two stops by subtracting the time spent on stops from the total time taken by the horse:

Time on road between two stops = Total time taken by horse - Time spent on stops

Substituting the values, we get:

Time on road between two stops = 60 minutes - 60 minutes = 0 minutes

Therefore, the horse did not spend any time on the road between two stops.

Answer

The horse did not spend any time on the road between two stops.
