If deanna starts running at 7: 30 and she runs for an hour and a half. how long does she end up running?

Hello!

Deanna starts running at 7:30, and runs for an hour and a half. Meaning, 1:30

To find out how long she ends up running, we must add the hour and a half to the time she started running:

7:30 + 1:30 = 9:00

Deanna ends up running until 9:00.

Deanna would be running up until 9:00 o'clock, this is because 7:30 plus I hr and a half equal to 8:60, and then that would turn into 9:00.

It will b. 975 because i’m guessin

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
