An ostrich. An run at a rate of 50 miles every 60 minutes. At this rate how long will it take an ostrich 15 miles?

50/60 = 15/x

Cross multiply and solve for x.

To find out how long it will take an ostrich to cover a distance of 15 miles, you can use the formula:

Time = Distance / Rate

In this case, the distance is 15 miles and the rate is 50 miles every 60 minutes. So, we can substitute these values into the formula:

Time = 15 miles / (50 miles / 60 minutes)

To simplify, we can multiply the fractions:

Time = 15 miles * (60 minutes / 50 miles)

Now, we can cancel out the miles:

Time = (15 * 60) / 50 minutes

Calculating this gives us:

Time = 900 / 50 minutes

Simplifying further, we have:

Time = 18 minutes

Therefore, it would take an ostrich approximately 18 minutes to cover a distance of 15 miles at a rate of 50 miles every 60 minutes.
