2.)Solve each formula for the variable indicated in red: C=2πr ( R is in red )
3.)Solve each formula for the variable indicated in red: V= 1/3 Bh ( B is in red )
4.) A black mamba travels 20 mi/h for 1/4 mile. How many seconds does it take the snake to travel 1/4 mile? Solve the distance formula for time. For which variables in the formula should you substitute 20 and 1/4. How many seconds are in an hour.

1. V = lhw

Divide both sides by lh:

w = V /lh

2. C = 2πr

Divide both sides by 2π

r = C/2π

3. V=1/3Bh

Multiply both sides by 3:

3V = bh

Divide both sides by h:

B = 3V/h

4. There are 4 1/4 miles per 1 mile.

20 x 4 = 80, so there are 80  1/4 miles in 20 miles.

There are 60 minutes per hour, so the snake travels 80 quarter miles per 60 minutes.

80/60 = 1 1/3 minute per 1/4 mile = 1 minute 20 seconds = 80 seconds.
