The formula for distance traveled is d = rt, where r is rate and 1 is time. What will be the value for d when an airplane flies at 420 miles per hour for three hours? A. d = 420 miles

B. d = 423 miles

C. d = 840 miles

D. d = 140 miles

E. d = 1260 miles

HELP ASAP​

d=rt

r=420 per hr, 3 hrs = 420/3= 140

t=1

d=140×1=140miles

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!
