Average speed = Total distance/Time
A = 550km/6.5hr
A = 84.6 km per hr
Answer:
108 = x
Step-by-step explanation:
multiple both sides by 24 and simplify
9 x 24 = 216/2=x
108 = x
The answer is B 864 ft squared.
1.
a. 8 x 7 x 1/2 = 56 x 1/2 = 28
b. 24 x 14 x 1/2 = 336 x 1/2 = 168
c. 5 x 12 x 1/2 = 60 x 1/2 = 30
d. 4 x 4.8 x 1/2 = 19.2 x 1/2 = 9.6
2.
two triangles: 2(4 x 8 x 1/2) = 4 x 8 = 32
rectangle: 15 x 8 = 120
total area: 32 + 120 = 152
