Distance by Pacing. In five trials of walking along a 90-m course on fairlylevel ground, a pacer for a survey party counted 51, 52.5, 51.5, 52.5, and51.5 strides respectively. He then started walking an unknown distance XYin four trials which were recorded as follows: 88.5, 89, 88, and 87 strides.Determine the following:1.a) Pace factor of the pacerb) Length of line XYc) Percentage of error in the measurement if the taped length of XY is 150.5meters.

Q1. During a 60 seconds period, a loop detector is occupied by vehicles for the following times for the following, 0.34s (car1), 0.38s (car2), 0.40s (car3), 0.32s (car4) and 0.52s (car5). Estimate the value of flow, density and velocity. You can assume that length of the loop detector is equal to 10 feet and the average length of all vehicles is 20 feet.

The pace factor of a random man was recorded to be 0.76 meters per step. If there is 2.7% margin of error with the use of his pace factor, what is the value of the probable error of the distance of a line measured using the man's pace factor if the recorded number of steps is 143.

3. A game requires that two children throw a ball upward as high as possible at the same point and then to run horizontally in opposite directions. The child who travels the greater distance before their thrown ball impacts the ground wins. One child throws the ball at his arm's height of 4 feet at a speed of 70 ft/sec and runs leftward at a speed of 16 ft/sec. The other child does the same but was able to throw better releasing his ball at a height of 6 feet at a speed of 64 feet second then runs rightw ard immediately at a speed of 17.8 ft/sec. Which child w ins the game?
Sir Alfonse sent out five students to measure a distance between two points marked on the ground using their pace factor. The students came up with the following five different values: 50.13, 47.90, 51.04, 50.47, and 48.22 meters. Assuming these values are equally reliable and that variations result from accidental errors, determine the most probable value of the distance measured.
A man and a woman both walked towards each other on a straight path but started at the opposite ends. Assuming they take the same step at a time, and that the woman is only 2/3 of the man's pace factor, and the length of the path is 100 meters. How many steps did they take before they were really close to each other if the man's pace factor is 0.76m/pace?
