1 hr and 25 minutes
Step-by-step explanation:add 3:15 with 30 min to get 3:45 then add 4:50 with 30 minutes to get 5:20
Hopefully this helps ^_^ part c is longer then 6:30
Difference between 4:20pm and 3:15pm = 1 hour and 5 minutes
You can use a numberline by skip counting by 30 minutes then by 5 minutes, then take away 30 minutes because of the 30 minute break.
3:15 pm - start of first showing.
30 minutes break;
20 minutes late - 2nd showing.
4:50 - start of second showing.
4:50 - 0:20 = 4:30 should be the start of the second showing.
4:00 - 4:30 = 1/2 hour break
3:15 - 4:00 = duration of the 1st showing. 45 minutes in all.
4:50 + 0:45 = 5:35 pm end of the 2nd showing.
Yes, the 2nd showing will be over by 6:30 pm.
because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
hans did not square the 40-unit side; he merely multiplied it by 2. incorrect.
