The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second
Step-by-step explanation:
We have to calculate his unit rate for both type of races
So,
<u>Unit rate for 400m race:</u>
Distance = 400m
Time = 43 sec
<u>Unit rate for 300m Race:</u>
Distance = 300m
Time = 31 sec
The difference between both unit rates is:
Hence,

Answer:
Step-by-step explanation:
We have two triangles and three rectangles.
The formula of an area of a triangle:
b - base
h - height
The formula of an area of a rectangle:
l - length
w - width
TRIANGLE:
b = 11 in, h = 7 in
RECTANGLE 1:
l = 11 in, w = 14 in
RECTANGLE 2:
l = 9 in, w = 14 in
RECTANGLE 3:
l = 8 in, w = 14 in
The Surface Area:
Substitute:
