“That’s what Mother Gunga thinks, is it,” he said, reading. “Keep cool, young ’un. We’ve got all our work cut out for us. Let’s see. Muir wired half an hour ago: ‘Floods on the Ramgunga. Look out.’ Well, that gives us—one, two—nine and a half for the flood to reach Melipur Ghaut and seven’s sixteen and a half to Lataoli—say fifteen hours before it comes down to us.”

This is from "The Bridge Builders" by Rudyard Kipling.

I don't understand the meaning of "seven’s sixteen and a half".

The character is doing math and saying it out loud. Here, "and seven's" means "plus seven is", as in, nine and a half hours plus seven hours makes sixteen and a half hours before the flooding reaches Lataoli.

9.5 + 7 = 16.5
