The speed limit is 35 mph. todd is stopped for
speeding and is fined $12 for every mile over
the speed limit. write an equation for the fine
that todd will have to pay. use fas the
variable for the fine, and s for the speed of the
car.

An equation for the fine  that Todd will have to pay  is f =  12(s -35)

Step-by-step explanation:

Given:

Speed limit = 35 mph

Fine amount for every mile over  the speed limit  =  $12

To Find:

An equation for the fine  that Todd will have to pay = ?

Solution:

The fine amount todd have to pay  =f

Speed at which todd travelled = s

Then

It is said that that the fine amount  $12 for every mile over  the speed limit

The speed beyond the speed  limit = (s -35)

Now the fine amount will be

f =  12(s -35)

f = 12s - 420

or

Step-by-step explanation:

Let S be the sum of the times for all winning team.

Given:

leg 1. 32 minutes 56 seconds.

leg 2. 42 minutes 28 seconds.

leg 3. 34 minutes 34 seconds.

leg 4. 39 minutes 2 seconds

We need to find the total time to run all four  legs of the marathon.

Solution:

Sum of the times for all winning team.

Substitute running times for all legs.

Now, we write the minutes and seconds separately.

Therefore, Total time taken by all four legs  or .
