Emil and Erika are playing a board game.
a) on Monday, they started playing at 17:36 and played for 45 minutes. What time was it when they finished?
b) on Tuesday, they played from 4:47 p.m. Until half past six. How many minutes did they play?
c) they played 33 minutes on Wednesday and finished with a quarter to six. What time was it when they started?

Result

a = 18:21
b =  43 min
c = 16:42

Step-by-step explanation:

$a=17+\frac{36}{60}+\frac{45}{60}=18.35=18:21$

$b=17\cdot 60+30-(16\cdot 60+47)=43\text{min}$

$c=17+1/4-\frac{33}{60}=16.7=16:42$
