How long would it take for this aircraft to cover a distance of 115 NM if it cruised at Mach .83?

31 mins
25 mins
20 mins
17mins

Any help would be greatly appreciated!
What Ghengis said for ATPL exams, or if you’re sat in the cockpit without a TAS readout…….Mach 0.83 equals roughly 8.3 miles per minute, covert to TAS, knock off the 45kts headwind and you’ve got a ball park figure. Useful for gross error checking.
