We know, area = length * width
Here, A = 582.25 in²
w = 17 in
Substitute their values,
582.25 = l * 17
l = 582.25 / 17
l = 34.25 in
In short, Your Answer would be 34.25 inches
Hope this helps!
Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;
The distance between the two cyclist when they begin biking away from each other = 7 miles
The first cyclist's speed = 12 miles per hour
The second cyclist's speed = 12 + b miles per hour
Therefore, we have;
The equation for distance covered, d = Speed × Time
The distance covered by the second cyclist in 45 minutes, is given as follows;
45 minutes = 3/4 hour
= (12 + b) × 3/4 = (3/4·b + 9) miles
The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.
