I have a tricky math problem here:

4 people have to get across a bridge in 19 minutes. However, they all go at different speeds and there is only 1 flashlight. The bridge can only hold 2 people at a time, and 1 must return with the flashlight to pass it off. 1 person can cross the bridge in 1 minute. The second can do so in 2 minutes. The third in 5, and the last in 10. How can they do this? scratch study
