suppose jay has travlled x miles,ben has travelled 8-x miles and they meet after time t
for jay: d=x mile, t=t hour and r=5mph
therefore x=5 t
or t=x/5 ...(1)
for ben: d=(8-x) mile, t=t hour and r=7mph
therefore 8-x=7 t
or t=(8-x)/5 ...(2)
from eqns.1 and 2
we have
x/5 = (8-x)/7
or 7x = 40-5x
or x = 40/12 = 3.333 miles
so jay travels 3.333 miles
and ben travels =8-3.333=4.67miles,so ben travels longer distance
combined distance travelled is 8 miles
time at which they meet = 3.333/5=.6666 hrs or 66.66 mins
