For this case, what we must do is calculate the speed of the runner.
We have then that the speed is given by:

Where,
d: distance
t: time
Substituting values we have:


Answer:
the runners unit rate is:

Answer:
A=90°,B=90°,C=90°,D=90°
Step-by-step explanation:
all of the numbers A-D add up to 360°
2.083333 yards are in 6 1/4 feet
Answer:
174 square centimetres
Step-by-step explanation:
The formula for finding the surface area of a rectangular prism is
SA = 2LW + 2LH + 2HW
Therefore surface area will be
= 2(11*5) + 2(11*2) +2(2*5)
= 2 * 55 + 2 * 22 + 2 * 10
= (110 + 44 + 20) square cm
Which gives you 174 square centimetres.
3/4 (x-12)=12
3/4x - 9= 12
+9 +9
3/4x=21
*3/4 *3/4
x= 15 3/4
and
3/4y-12=12
+12 +12
3/4y = 24
*3/4 *3/4
y= 18
