A camel travels 1/3 of a mile in the same time that a horse travels 5/7 of a mile. How many times slower does the camel travel than the horse?

To solve this problem, we need to find the ratio of the speeds of the camel and the horse.

Let's assume that the speed of the horse is x miles per hour.

The camel travels 1/3 of a mile in the same time that the horse travels 5/7 of a mile.

The speed of the camel can be calculated by dividing the distance traveled by the time taken:
Speed of the camel = Distance/Time
Speed of the camel = (1/3) mile / T hours

Since the horse travels 5/7 of a mile in the same time, the speed of the horse can be calculated as:
Speed of the horse = Distance/Time
Speed of the horse = (5/7) mile / T hours

The ratio of their speeds is:
Speed of the camel / Speed of the horse = (1/3) / (5/7)
Speed of the camel / Speed of the horse = (1/3) * (7/5)
Speed of the camel / Speed of the horse = 7/15

So, the camel travels 7/15 times slower than the horse.
