"hello students i am rita umass lito
tutor
and the today's question is rashmi has a
road map with a scale of
one centimeter representing 18 kilometer
she drives on a road for 72 kilometer
what would be her distance covered on
the map
so there are two distance one is actual
distance
and the other is one is
actual distance
and the other is
distance on map distance
on map so there are
two distance actual distance
rashmi has a road map with a scale of
one centimeter representing 18 kilometer
so actual distance is 18 kilometer and
actual distance is 18 kilometer and
distance on map
is one centi meter
and she drives on a road for 72
kilometer actual distance is 72
kilometer and we have to find
her distance covered on map that we can
take up
x okay we let it be x so
obviously it is a case of direct
proportion
it is a case of direct proportion
it is a case of direct proportion
or we can save variation
it is a case of direct proportion and in
direct proportion
x by y is equal to
okay constant okay now we apply this
formula
18 by 1 is equal to
72 by x now we cross multiply
each other we cross multiply
each other then we get an equation 18
multiply
x is equal to 72 multiply one
so the value of x is 72
divided by 18. now 18
and 18 fours up
so x is equal to 4 70
meter so this is our answer i hope you
