Problema Solution
IN 10hrs A walks 5 miles more than B does in the same time; and in 8 hrs B walks 8miles more than A does in 4 hrs. how many miles does each walk per hour?
Answer provided by our tutors
let A walks at xmile/hr
whille B walks at y miles per hour
now,
in 10 hours
a walks=10*x
B walk=10*y
10x=10y+5--(1)
=> 10x-10y=5
and agian
8y=4x+8
=> -4x+8y=10--(2)
solve (1) and (2)
x=3.5miles/hr and y=3miles/hr
