Answer: please mark me brainliest

In 1 hour, the first train will have traveled 60 miles.

Let t be the time before the first train catches up to the second. Then:

60t+60=80t

20t=60

t=3 hours

Morgarella [4.7K]

Answer: 24

Step-by-step explanation:

Colleen painted 7 windows, some of which were her mother's.

Her dad painted 7+1 (8) windows, and that is twice as much as what her mother was supposed to do. Her mother was supposed to do 4 windows. That means Colleen's share was 3 windows.

If all the kids had to do an equal amount of windows, than each kid had to do 3 windows.

8+7+3+3+3=24
