T to the second power - 12w ÷ x

t=8
w=1/2
x=3

62

Step-by-step explanation:

Since we know what each value of the three variables are, you can substitute each variable in the expression to get:  

÷ 3  

Simplify to get:

64 - 6 ÷ 3

Solve the rest:

64 - 2  →  62

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in
