Andrew drove his car 234 km from Dawson to Mayo in Yukon Territory in 3 h. Brian drove his truck along the same route at an average speed of 5 km/h greater than Andrew’s average speed. How much less time did Brian take, to the nearest minute.

Answer 1

Andrew drove at 78 km/h

Brian drove at 83 km/h

234/83 = 2.819 hours, or 169 minutes.

180-169=11
