Christy c = 90 min
kids k = 120 min
total time t = ?
I would do : 90+120 = 210 then divide that by 2 which equals 105 min
For uniform, the mean is:
<span>x¯ = (<span>590.0+590.9) 2</span></span>
The variance is:<span>
σ = sqrt [ (<span><span>n2−1) /</span>12 ]
</span></span><span>
Where n=10.
The answer would be 590.45
I hope my answer has come to your help. Have a nice day ahead and may God bless you always!</span>

Answer:
30 km/h
Step-by-step explanation:
usual speed= x km/h
increased speed= x +10 km/h
distance= 360 km
time difference= 3 h
- 360/x= 360/(x+10) +3
- 360/x= (360+ 3x+30)/(x+10)
- 360(x+10)= x(390+3x)
- 360x+3600= 390x+ 3x²
- 3x² + 30 x -3600=0
- x²+10x-1200=0
- x=30 km/h
