I’m pretty sure it’s linear!
A = velocity / time
b) 40m/s
13m / 3s = 4.33 m/ss

Step-by-step explanation:
Given expression:
13) 
15) 
Write the expressions in radical form.
Solution:
For an expression with exponents as fraction like

the numerator
represents the power it is raised to and the denominator
represents the nth root of the expression.
For an expression with exponents as negative fraction like

We take the reciprocal of the term by rule for negative exponents.
So it is written as:

using the above properties we can write the given expressions in radical form.
13) 
⇒
[Using rule of negative exponents]
⇒
[writing in radical form]
15) 
⇒
[Since 2nd root is given as
in radical form]
Answer:
30 miles
Step-by-step explanation:
The rate is distance /time
50 /15 =10/3 miles per hour
To find the distance traveled in 9 minutes, multiply the rate by the time
distance = 10/3 *9 = 30
30 miles
