Two Olympic runners are running clockwise around an indoor track. They both can run a lap in less than one minute. If they start at the same time and at the same position, after 4(2/3) minutes, the faster runner will have covered 1 more lap than the slower runner, with each runner having covered an integer number of laps in that time. The time it takes each of them to finish one lap is an integer number of seconds. How many more seconds does it take the slower runner to finish one lap compared with the faster runner?

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
