What type of counting problem is this? If Jackson is at the store and can buy any 3 fruit (the store sells apples, oranges, pears, bananas, strawberries, blueberries, and kiwis), how many different collections of fruit can he choose?
a. Combination with repetition
b. Permutation with repetition
c. Combination without repetition
d. Permutation without repetition

i believe it is d because it can have a variety of the fruits and without repetition it gives Jackson different choices

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
