= - 10
<span>169 = 13^2
</span><span>so will get
13^2 *(12^2)^25
---------------- so simplify by 13^2 and will get
13^4
12^50

Distance from New Orleans to Boston and back is the same.
t - time from New Orleans to Boston
(t-1) - time from Boston to New Orleans
40t - distance between New Orleans and Boston.
80(t-1) - distance between Boston and New Orleans.
40t = 80(t-1)
40t = 80t - 80
40t = 80
t=2 h
To find average speed we need to find all distance and divide it at all time.
All distance = 40t +80(t-1) = 120t - 80
All time = t+(t-1)= 2t-1
Average speed =(120t - 80)/(2t-1)
Now we can substitute t=2.
Average speed =(120*2 - 80)/(2*2-1)=53.33 m/s
Answer:
Yes
Step-by-step explanation:
Most commutes to work or errands are about 8 to 32 minutes - averaging at around 20 minutes.
