Answer Posted / sunil
only thing that can be deduced from this is that the person
meets its driver at 6:50pm (since the driver saved total 20
min it must have saved 10 min for each side )since the man
cover that distance in 80min(from 5:30pm to 6:50pm ie 80 min
)to cover a distance that his driver would cover in only 10
min ,so from this data we can only conclude the ratio of
speed between the man and his driver is 1:8
