Answer:
2.5 miles per minute
Step-by-step explanation:
speed = distance ÷ time
speed = s
distance = 25 miles
time = 10 minutes
s = 25÷10
s = 2.5 miles per minute
24 square units is the answer
Cross multiply: 20 * b = 45 * 34
Simplifying: 20 * b = 45 * 34
Multiply 45 * 34: 20b = 1530
Solving: 20b = 1530
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Divide each side by '20': b = 76.5
Simplifying: b = 76.5
