Answer: A. 76 sq. units
Step-by-step explanation:
1. You can use the following formula for calcualte the area of the parallelogram:
Where 
is the base and 
is the height of the parallelogram
and 
2. The formula for calculate the area of a rectangle is:
Where 
is the base and 
is the height of the rectanngle.
and 
3. Then, the area of the figure is the sum of the area of the parallelogram and the area of the rectangle:
Answer:
7 minutes 48 seconds.
Step-by-step explanation:
Average speed for the whole journey is
distance / time, so
105 = (2*80)/ (t + t2)
where t is the time when it is moving and t2 is the time it stays at town Q.
Time for journey P to Q
= distance / speed
= 80 /120
= 2/3 hours,
Time for journey Q to P
= 80/110
= 8/11 hours
So t = 2/3 + 8/11
= 46/33 hours.
- and substituting in the equation for the whole journey:
160 / (46/33 + t2) = 105
105*46/33 + 105*t2 = 160
105 t2 = 160 - (105*46)/33
= 160 - 146.364
= 13.636
t2 = 13.636/105 = 0.1299 hours.
= 7 minutes 48 seconds.
