You travel at an average speed of 20 km/h in a straight line to get to your grandmother's house. it takes you 3 hours to get to her house. how far away is her house from where you started ?

Distance = Speed x Time

Therefore distance = 20 x 3

Grandma's house is 60 km away from where you started.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
