The distance an object travels is determined by how fast it goes and for how long it moves. if an object’s speed remains constant, the formula is d=r+t when d is the distance, r is the speed, and t is the time. a satellite is orbiting the earth at the rate of 25 kilometers per minute. how far will it travel in two hours?

Well,

if d = r + t, then

d = 25 + 120. 

So, d = 145 km/hr. 

But, if d = r(t), then

d = 25 (120)
and
d = 3000 km/hr

I hope this helps and I'm sorry if I told the wrong answer. The reason why I did multiplication too is because I know as multiplication, but I could b having a brain fart. But go with the first answer. 

Xis equal to three

Hello!

the answer is:

the correct option:

b.

why?

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!
