62,3756 is the number of feet he ran. Divided by 5280, that is 12.075 miles in 70 minutes. Divide 12.075 by 70 to get the miles per minute(0.1725). Then, multiply by 60 to get 10.35, the answer. Therefore, Sam ran at 10.35 miles per hour.
Yep... so they says that the area of the extended leaf is 18+6x... You know that the area is length into breath... here the breath doesn't change.. so it'll be 3ft... can get the length by dividing area by 3... that is 6+2x... Now the new length wil be 2times that plus the previous 6ft length
