Answer:

0.4 second

Step-by-step explanation:

The formula D = st is the formula that can be used to substitute in the values (which is already in the problem).

If the speed is 175 meters a second and the distance is 70 meters, than that means 70 = 175t.

(I substituted 70 for distance, or D, and 175 for speed, or s).

Divide 175 on both sides in order to isolate the variable (t), which is 0.4 second.

The time taken for the hurricane to reach the shore would be 0.4 second.

Solve the equation or formula for the indicated variable. S=3r^4t, for t

algol [13]

we are given

$S=3r^{4t}$

Since, we have to solve for t

so, we will isolate t on anyone side

divide both sides by 3

$\frac{S}{3} =r^{4t}$

now, we can take ln both sides

$ln(\frac{S}{3}) =ln(r^{4t})$

we can simplify it

$ln(\frac{S}{3}) =4tln(r)$

divide both sides by 4ln(r)

$t=\frac{ln(\frac{S}{3})}{4ln(r)}$ ..............Answer
