A cyclist travels 2 miles in 10 minutes and then a further 6 miles in 20 minutes without stopping. Calculate the cyclist's average speed in mph

Given :

A cyclist travels 2 miles in 10 minutes and then a further 6 miles in 20 minutes without stopping.

To Find :

The cyclist's average speed in mph.

Solution :

We know, average speed is given by :

Hence, this is the required solution.

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 %
