The formula d= rt gives the distance traveled in time t at rate r. A bicyclist rides for 1.5 hours and travels 25 miles. what is the average rate of speed? A. 26.5 miles per hour
B. 16.7 miles per hour
C. 23.5 miles per hour
D. 37.5 miles per hour

Using then given formula replace the letters with the given information.

25 miles = r x 1.5 hours

To find r divide both sides by 1.5:

R = 25/1.5

R = 16.7 miles per hour

The answer would be B.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
