Write 4 cubic miles in exponential notation

we have to write

4 cubic miles in exponential form

exponential forms means 10^n form or 2^3 or 3^4 etc

Here , we have cubic

It means that we put exponent ^3 over miles

so, we can write

4 cubic miles in exponential form as

...........Answer

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

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
