Answer:
48 hours
Step-by-step explanation:
you would divide the total by the part (328.80/6.85) and that would give you her hours. hope this helps
 
        
                    
             
        
        
        
Answer:
1275
Step-by-step explanation:
Because 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48+49+50 = 1275

Answer:
The time will depend on the number of people who move on each trip from the point of origin to the destination. If done at the maximum speed allowed using 100 vehicles of 50 seats each, the evacuation would be done in 63.68 hours
Step-by-step explanation:
Population = 91,000 ppl
Speed limit = 60 mph
Distance = 21 miles.
1. <em>Assuming that people is evacuated at the max. speed allowed, it means that each trip will take</em>:
 T = D/V
 D= 21 miles
 V = 60 mph:
 
So;
 T = 21 miles / 60mph
 T= 0,35 h
2. Asumming that we are going to use an amount of 100 vehicles  with 50-seats in each trip for evacuating people, it means that we could evacuate 
500 people every 0,35 h ≈ 1,429 ppl/hour <em>(evacuation rate)</em>
To know how long it would take us to evacuate 91,000 people under these conditions, we would have to divide the total amount by the previously calculated evacuation rate
T= 91,000/ 1,429 = 63,68 hours
