Average growth= 11.20 feet
Step-by-step explanation:
<u>First, we need to calculate the total growth during those 312 years:</u>
<u></u>
Total growth= 3,512 - 18
Total growth= 3,494 feet
<u>Now, the average growth:</u>
<u>Average growth= total growth / number of years</u>
Average growth= 3,494 / 312
Average growth= 11.20 feet

It will take 3 hours 6 minutes 40 seconds for the cars to be 420 miles apart.
Step-by-step explanation:
Step 1; The cars are traveling in the opposite direction at different speeds. One is going north at a speed of 75 mph while the other is going 60 mph. So for every hour, the cars are traveling they increase the distance between in between themselves by 75 miles + 60 miles = 135 miles.
Step 2; Assume that in x hours the distance between them is 420 miles. To calculate x we divide the distance to be traveled by the distance being traveled every hour.
x = distance to be covered / distance being traveled every hour
= 420 / 135 = 3.11 hours
We multiply the 0.11 hours with 60 to convert it into minutes. 0.11 × 60 = 6.66 minutes and if we do the same for seconds, 0.66 minutes × 60 = 40 seconds.
