So, we need to do the distance she travelled (21 miles) divided by the rate at which she travelled (4 hours). Therefore, because 21 divided by 4 is 5.25, she biked at a speed of 5.25 mph (Miles per hour). So, if she bikes 5.25 miles every hour we can divide 42 by 5.25 to get the time it would take her to travel 42 miles. Now, 42 divided by 5.25 equals 8, so that means for Shelly to bike 42 miles at her average speed of 5.25 mph, it would take her 8 hours.
A = ((B+b)*h)/2
A = ((6+4)*3)/2
A = 15
take square root and subtract y2 from y1 and x2 from x1
12000000 bytes is one frame, then you multiply that by 24 to get one second (288000000 bytes). Then I just multiplied that by 60 to get one minute (17.28 billion). After that I multiplied by sixty to get 1037000000000000 (1.037 trillion) so its 1.037 trillion bytes.
