Answer 2

answer- Both girls come to the other side of the river.The 1 girl goes away. She stays at the 1 side of the river while one explorer crosses the river. The 2 girl gets to the 1 side of the river, gets the 1 girl and crosses. 1 explorer crossed.
When both of the girls are on the second side. 1 girls goes. She stays at the 1 side of the river while the 2 explorer crosses. The explorer hands the rowboat to the 2 girl. She crosses, gets the 1 girl and they both head to the 2 side of the river. 2 explorers crossed.
And like this it goes on and on, all the way until all of the explorers crossed the river. Total:28 trips back and forth. Hard work lol.

Answer 3

problem---A team of 7 explorers came to a river they needed to cross.They found two girls who had a rowboat. The boat could only carry two girls or 1 explorer at a time. How can all of the explorers get across the river using the girls' rowboat? How many trips would it take? Both girls have to get to the starting side.
