The number of hours that the two trucks will be  676.5 miles apart is 11 hours.

Number of hours

Distance = Rate x Time

D =  676.5 miles

Hence,

D = Average rate x Time

676.5 miles miles = (62mph + 61mph)/2 x Time

676.5 miles / (123mph/2)

676.5 miles / 61.5mph

= 11 hours

The total time is 11 hours, which means that each driver will drive for 5.5 hours.

Proof:

62mph x 5.5h + 61mph x 5.5h

= 341m + 335.5m

=676.5  mile

Inconclusion the number of hours that the two trucks will be  676.5 miles apart is 11 hours.
