Answer:
She lost $2550.
Step-by-step explanation:
She bought 37 meters at $750/m.
37 m * 750/m = $27,750
She paid $27,750
She sold 28 m at $900/m
28 m * $900/m = $25,200
She sold $25,200
$25,200 - $27,750 = -$2550
2553
the average velocity is 86 km/h for the trip
from the definition of average velocity
average velocity = distance covered / time required = 1682 km /(19 h + 28 min/60 min/h) = 86 km/h
therefore the average velocity is 86 km/h for the trip
-1 is the remainder
