A woman walks a constant speed of 4.5km per hour. How long will it take her to walk 10 km? Use the formula d=st. write the answe
r in hours and mintues rounded to the nearest minute.
2 answers:
d =st
distance = speed * time
10 = 4.5 * t
divide each side by 4.5
10/4.5 = t
100/45 = t (can't have a decimal in a fraction so I multiply by 10/10)
divide top and bottom by 5
20/9
2 and 2/9 hours
to get minutes multiply 2/9 by 60
2/9 * 60
120/9
13 3/9
13 1/3 minutes
2 hours 13 1/3 minutes
to the nearest minutes
2 hours 13 minutes

Step-by-step explanation:
Number of distinct Toppings wanted = 4
Total number of vegetarian topping = 8
To choose 4 distinct toppings from a total of 8
Using permutation :
