Answer: Exspand it by 3 blocks
Step-by-step explanation:
There is four 1/4's per mile.
This means you run 1 mile in 3 x 4 = 12 minutes.
Multiple minutes per mile by total miles:
12 minutes per mile x 26.2 miles = 314.4 minutes.
1 hour = 60 minutes:
Divide total minutes by 60 to get hours:
314.4 minutes / 60 minutes per hour = 5.24 hours.
Multiply the decimal part of the hour by 60 to get the minutes:
0.24 x 60 = 14.4 minutes = 14 minutes and 24 seconds.
Total time = 5 hours, 14 minutes and 24 seconds.
Answer:
990 cars
Step-by-step explanation:
Find how many cars pass through at 6am, t=0:
r(0)= 300+600(0)-90(0²) = 300
Find how many cars pass through at 9am, t=3:
r(3)= 300+600(3)-900(3²)=300+1800-810=1290
Find the difference (how many cars pass between 6am and 9am): 1290-300=990
