Hi!
Let's make a small chart
18:15 left town B
19:15 1 hour
20:15 2 hours
21:15 3 hours
Since they actually arrived at 21:05, and not 21:15, we know it took more than 2 hours, but less than 3 hours.
Subtract the extra time
21:15-21:05 = 00:10
Since there are 60 minutes in an hour, (60-10=50) we know it took 2 hours and 50 minutes.
Another way to solve this would be to convert the times to decimals, and subtract,
21.05-18.15 = 2.9
Then convert the decimal to the time.
9/10 of an hour = 50 minutes
It took 2 hours and 50 minutes
Hope this helps! :)

Answer:
For employee 1 = 2.5
For employee 2 = 8.6
For employee 3 = 4.4
For employee 4 = 10
For employee 5 = 24
Step-by-step explanation:
number of hour worked= H
total money earned =T
earning per hour =M
we have the following relations:
H =T/M
M =T/H
For employee 1 we have:
T=23.75$
M =9.50$
We calculate H by using the above equations, so we have:
H =23.75/9.50= 2.5
For employee 2 we have:
T=28.38 $
H =3.3
We calculate M by using the above equations, so we have:
M =28.38/3.3 =8.6
For employee 3 we have:
T=38.50$
M =8.75$
We calculate H by using the above equations, so we have:
H =38.50/8.75= 4.4
For employee 4 we have:
T=55 $
H =5.5
We calculate M by using the above equations, so we have:
M =55/5.5=10
For employee 5 we have:
T =60 $
H =2.5
We calculate M by using the above equations, so we have:
M =60/2.5 = 24
