Answer:
4909 m/hr
6000 m/hr
Step-by-step explanation:
Last Year :
Distance = 300 m
Time = 3 2/3 minutes
Speed per hour = distance / time
Time in hour = 11/3 ÷ 60 = 0.0611111 hour
300 / 0.0611111 = 4909.0918 m /hr
= 4909 m/hr
This year :
Distance = 200 m
Time = 3 minutes
Speed per hour = distance / time
Time in hour = 3 ÷ 60 = 0.0333333 hour
200 / 0.0333333 = 6000.0060 m /hr
= 6000 m/hr
2 and three because the have the same length and all sides are the same

<em>f = 16 females</em>
- Step-by-step explanation:
<em>f/m = 4/3 => m = 3f/4</em>
<em>f + m = 28</em>
<em>replace m</em>
<em>⁴⁾f + 3f/4 = ⁴⁾28</em>
<em>4f + 3f = 112</em>
<em>7f = 112</em>
<em>f = 16 females</em>
