Answer:
width = 6k², length = 5k + 1
Step-by-step explanation:
Given
A = 30k³ + 6k² ← factor out 6k² from each term
= 6k²(5k + 1)
Since area = width × length , then
width = 6k² and length = 5k + 1
The number of hours Nick took to reach the shopping mall in terms of r is ; 3.14 hours.
<h3>What is rate?</h3>
Rate is a measure of a quantity using another quantity as the basis.
Analysis:
speed travelling on foot = r
distance travelled on foot = 5 miles
time taken = 5/r
speed travelling on bicycle 80 percent faster than on foot is 1.8r
distance travelled on bicycle = 8 miles
time taken = 8/1.8r = 40/9r
total time taken to get to the mall = 5/r + 40/9r = 85/9r
speed while walking = 3 miles per hour = r
time taken = 85/9 x 3 = 3.14 hours
In conclusion, number of hours Nick took to reach the shopping mall in terms of r is 85/9r is 3.14 hours.
