An object travels 4/5 mile in 30 minutes. How fast does she travel in 1 hour?

So,

If you mean "speed per hour," then we just have to double the numerator of the fraction.

4 * 2 = 8

The object's speed is 8/5 miles per hour or 1.6 mph.

sorry man i accidentally pressed yes my bad

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
