Emily takes a trip, driving with a constant velocity of 89m5 m/s to the north except for a 22 min rest stop. if emily's average velocity is 77.8 m/s to the north, how long does the trip take?

Emily moves with speed 89.5 m/s

let it travel for time "t" so the distance covered by it

now the average speed is given as

here total time of the journey will be given as

now we have

so it will move for t = 2.44 h

so the total time of the trip would be given by adding waiting time or time of stop

so his total time of journey is 2.8 h

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."
