Can someone please help me with question no. 3.2.2

so the train departed Durban at 18:30 in 24hours format, or namely 6:30pm, and arrived at Kimberly at 14:50 on the next day, namely 2:50pm Thursday.

let's see, from 6:30 to 7pm is 30 minutes

from 7pm to 12am or 00:00 is 5 hours

and from 12am to 2:50 or namely 00:00 to 14:50 is well, 14 hours and 50 minutes

if we add the hours first, that'd be 5 + 14 = 19, and then we add the minutes that'd be 30 + 50 = 80 minutes, so that'd be a total of 19 hours and 80 minutes, wait a second!!!, 80 minutes is really 60 + 20, or 1 hour and 20 minutes, so that'd make it 19 hours plus 1 hour and 20 minutes, 20 hours and 20 minutes.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
