an ultra marathon athlete can run long distances at an average speed of 7 1/2 miles per hour. at that rate, how long will it take him to run 50 miles

Answer 1

To find out how long it will take the ultra marathon athlete to run 50 miles, we can use the formula:

Time = Distance / Speed

Distance = 50 miles

Speed = 7 1/2 miles per hour

Plugging in the values, we get:

Time = 50 miles / 7 1/2 miles per hour

To divide by a fraction, we can multiply by its reciprocal:

Time = 50 miles * (2/15 hours per mile)

Now we can simplify the equation:

Time = (50 * 2) miles / 15 hours

Time = 100 miles / 15 hours

Finally, we can divide:

Time = 6.67 hours

Therefore, it will take the ultra marathon athlete approximately 6.67 hours to run 50 miles at an average speed of 7 1/2 miles per hour.
