Answer:
27525.4902
Step-by-step explanation:
First need to add the total number of employees:
14+11+17+3+5+1=51 
Now multiply the salary for each number of employees then add to have the total:
14x21000+11x22800+17x24800+3x32200+5x38500+1x148300= 1403800
Now to obtain the mean value just divide the total salary by the total number of employees:
1403800/51= 27525.4902
the mean salary is $27,525.49
 
        
             
        
        
        
250 seconds because it takes Mary 50 seconds to get around the track (300feet/6ft/sec) and it takes Peter 300 seconds to get around the track (300ft/1ft/sec) so if you subtract the fastest time from the shortest time you get the amount of time that Mary had to wait for Peter to get there, so after 250 sec (300sec-50sec) Peter, Paul, and Mary are reunited.
