Hey! To do this, we need to multiply 4.5 x 10² by 3.2x10^6 by 365 (days in the year) to get our answer.
Answer: 525,600,000,000
Davie will take 80/20 = 4 hours to finish the tour. Horatio has only 2 and 1/2 hours to cover the same 80 miles. (80)/(2.5)= 32 miles per hour.
The slope formula is:
Where (x2,y2) is the rightmost point and (x1,y1) the other point to calculate the slope
The rightmost point in this case is (5,7) because 5 is greater than -3
So
Distribute
a(b+c)=ab+ac
2(10-r)=20-2r
now we have
8+20-2r
28-2r
