Answer:
No, They will do it in more than an hour
t=1,1 h
Step-by-step explanation:
Vh=1mile/12min, Vt=1mile/15min They will meet to same time th=tt
sh=x, st=10-x, so V=s/t we have Vh=sh/t ; Vt=st/t ; t=(sh/Vh) = (st/Vt);
; so 
: if Vh=sh/t then 
Note: V=s/t : but in this case are 12 min (t) per mile (s), so 
a=3
a6=43
a+6d=43---------1
substituting a=3 in eq 1
a+6d=43
3+6d=43
6d=43-3
d=40/6
d=20/3
so first 5 no's are a, a+d, a2+d,a3+d, a4+d
a=3
a+d=3+20/d
i think u know after this
Hope it helps u
