To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
Answer:
A. One solution
Step-by-step explanation:
To find out, we solve the equation.
6 - 3x = 12 - 6x
Add 6x to both sides. Subtract 6 from both sides.
3x = 6
Divide both sides by 3.
x = 2
Answer: A. One solution
330 x 4 / 100 = 13.2 lbs
<span>4 lbs ------0.25
13.2 lbs ......?
13.2 x 0.25 / 4 = 0.825 = 0.83
answer
83 cents

Best deal would be 4.95 for 3 because if you divide the numbers you end up paying more money for the 4 sandwiches. For comparison heres my results
$4.95 for 3 - $1.65 each
$6.72 for 4 - $1.68 each
