A 1939 Ford heads out of town traveling at 40 mph. Three hours later a 1957 Chevy follows traveling at 70 mph. How long will it

4 hours

using the formula

distance = speed × time (t)

the Ford will have travelled 3 × 40 = 120 miles before the Chevy leaves

the Ford's distance can be modelled as

distance = 40t + 120

the Chevy's distance can be modelled as

distance = 70t

equating the right sides and solve for t

70 t = 40t + 120 ( subtract 40t from both sides )

30t = 120 ( divide both sides by 30 )

t = 4

the Chevy catches up with the Ford after 4 hours

On which interval is the average rate of change for bicycle production the greatest? A) 1950 to 1960 B) 1960 to 1970 C) 1970 to
Alborosie

Answer:

D) 1980 to 2000

Step-by-step explanation:

Finding the average rate of change in each interval to determine the greatest one.

Production per interval

1950-1960 = (21-11) \ million = 10 million

1960-1970 = (41-21)\ million = 20 million

1970-1980 = (71-41)\ million = 30 million

1980-2000 = (161-71)\ million= 90 million

Rate of change (1950-1960)= \frac{10}{11} \times 100= 90.90\%

Rate of change (1960-1970) = \frac{20}{21} \times 100= 95.23\%

Rate of change (1970-1980)=  \frac{30}{41} \times 100= 73.17\%

Rate of change (1980-2000)= \frac{90}{71} \times 100= 126.76\%

∴ rate of change between 1980 to 2000 is 126.78%
