## Homework Statement

A motorist drives north for 35.9min at 73.3km/hr and then stops for 15.4min. He then continues north, traveling 114.5km in 1.93hr. What is his average velocity?

## Homework Equations

avg velocity = xf - xi / time

## The Attempt at a Solution

35.9 min * (1 hr / 60 min) = 0.5983 hr

0.5983 hr * (73.3 km / hr) = 43 .858 km

total time = 0.5983 hr + 1.93 hr + 0.257 hr = 2.785 hr

avg velocity = xf - xi / time

= 114.5 km - 43.858 km / 2.785 hr

= 25.37 km /hr N

which is actually incorrect because the answer is meant to be 56.9 km /h N.

What am i doing wrong ?
