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.

Andrew drove at 78 km/h

Brian drove at 83 km/h  

234/83 = 2.819 hours, or 169 minutes.  

180-169=11

b is the answer that makes most sense

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
