I just started Calculus 2, the topic we're on is estimating with finite sums.
I seem to be having a hard time with this problem in my textbook
Distance from Velocity data
The accompanying table gives data for the velocity of a vintage sports car accelerating from 0 to 142mi/h in 36 seconds(10 thousandths of an hour).
Use rectangles to estimate how far the car traveled during the 36 sec it took to reach 142mph
This one I managed to solve pretty easily using using upper and lower sums.
The shortest possible distance :
D= 0.001(0+40+62+82+93+108+116+125+132+137)= .798 mi
The longest possible distance:
D=0.001(40+62+82+96+108+116+125+132+137+142)= 0.94 mi
Roughly how many seconds did it take the car to reach the halfway point? About how fast was the car going?
this is the problem I'm having. I'm not sure where to start. I thought I could use halfway point= D/2 then work from there but I'm completely unsure on where to take it from there. A hint in the right direction would be awesome, I'm not looking for someone to solve the problem but feel free anyways.
