Use the velocity formula and solve for time.v=d/t
t=d/v
Substitute your variables and solve.
65 mi/hr = 65 / 3600 mi/second
25 mi / ( 65/3600) = 1384.6 seconds
9(7k-4)-2(7k-12) so first separate these two parts of it ok. 9(7k-4) the - and 2(7k-12) so first let’s do 9(7k-4) multiply 9*7 to get 63k and 9*4 to get 36. So now u have 63k-36. Let’s do the 9(7k-12) now. Same thing. 2^7=14 then 2*12 = 24 which leaves u at 108. So now if u put i together it’s (63k-36)-(14k-24) soooo 63k-14k= 49k and 36-24 = 12 so ur answer is 49k-12 !!! Hope that helps man
0.882 would be the answerrr
