The bridge is strong enough to support two people at a time and torch is required to cross bridge. Not all the people take the same time to cross the bridge.

1 comes back with torch : 1 min
7 and 10 cross the bridge : 10 min
2 comes back with torch : 2 min
1 and 2 cross the bridge : 2 min

Total time = 2 + 1 + 10 + 2 + 2 = 17 mins
