Place a dot on the 2nd line (4:05) on the timeline. Next, count each line by 5 as you leave until you count to 60 (by 5s), place a dot at 5:05 (one hour or 60 minutes). Now, count by 5s until you count to 45 and place a dot on 5:50. Thus, the answer is 1 hour and 45 minutes.
Answer: 1 hour and 45 minute
Yes, this is reasonable because he started at 4:05 pm and ended at 5:50 pm which is exactly 1 hour and 45 minutes later during the evening.
b) He finished in 1 hour and 45 minutes. One hour equals 60 minutes, thus, 60 minutes + 45 minutes = 105 minutes.
Answer: 105 minutes
{hint: start counting as you leave each dot do not count the dot which you start at)
