Dialog

Three guys have to be somewhere before a specific time to pick up something, but they end up in a traffic jam on the way.

Guy #1: What are we going to do? We have to be there within five hours and we still have 290 miles to go.

Guy #2: Ben, can't you call the guy and ask him if there's any possibility that we can come by later? (than the deadline)

Guy #3/Ben: I can try.

Please tell me if this dialog is completely clear and natural for the context. Thank you.
