Given a time of 3:59.37 for a mile run, this translates to 3 hours and 59.37 minutes. To convert this entirely into hours: 3 hours + 59.37 minutes (1 hour / 60 minutes) = 3.9895 hours. Thus, the average speed can be calculated as: average speed = 1 mile * (1.61 km / mile) / 3.9895 hours. Consequently, the average speed equals 0.4 km / hour.

tester [12383]
The height of the building, which is 100 ft, is four times greater than the shadow it casts, measuring 25 ft. Similarly, by maintaining this ratio, a person whose shadow is 1.5 ft tall will stand at four times that length, resulting in... 4 × (1.5 ft) = 6.0 ft. Therefore, the person's height is 6 ft.

20.7 degrees C
Step-by-step explanation:
The simplest way to approach this is with a calculator or paper. (it's straightforward math) To begin, start with 19.4. Then, it increases by 3.8. Adding this to 19.4 results in 23.2, but then it decreases again by 2.5 degrees. Thus, from 23.2, subtract 2.5 to get 20.7 degrees.
