Step-by-step explanation:

Answer 2

Answer:

given data :

4 emergency exits

53 passengers on board

requires 8 seconds per passenger to evacuate through one exit

Number of passengers evacuated for every 8 second = 4 (since 4 exits )

total time to evacuate all the passenger is

112 seconds

(104 seconds to evacuate 52 passengers through 4 exit and 8 sec for last passenger)

52÷4=13 passengers from each exit and last passenger alone

(13×8 =104 sec )+ 8 second=112 second
