In two hours, holden completed 3/4 of the race. how long will it take holden to complete the entire race?

2 hours and 40 minutes

Step-by-step explanation:

we need to find how much time it takes to complete the race if in two hours holden completed 3/4, the information is this:

hours    race

  2          3/4

   x            1

where x is the unknown hours that takes to complete 1 race.

Using rule of three:

we multiply  the cross quantities (2 by 1) and then divide by 3/4:

this is 2 hours plus 0.666 of hour.

0.666 of hour is equal to of hour, and since one hour has 60 minutes:

the total time is 2 hours and 40 minutes.

abde or 1,2,4, 5 is the answer

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
