How long did it travel at hypersonic speeds

300 miles was the reported test distance.

After release from an aircraft, the first stage boosted the vehicle to the expected scramjet ignition envelope. From there the missile’s Northrop Grumman scramjet engine fired up and propelled the cruiser to speeds greater than Mach 5 (five times the speed of sound) for more than 300 nautical miles and reaching altitudes higher than 60,000 feet.

Yeah, I just realized that number seemed way off and was about to edit my comment. ~5 minutes is correct.
