Answer:
30seconds
Step-by-step explanation:
if it takes 2 seconds to walk 3steps then in 30 seconds she should have walked 60 steps.
Number 3 is a because for every hour (x) the train travels 50 miles (y) so the total distance will be 50 times the number of hours (50x)
There are a total of 33 students in the class (21+12=33). There are 12 boys in the class so the chance of drawing a boys name would be 12/33 which reduces to 4/11. This means you will draw a boys name 4 times for every 11 draws. To find the percent probability, just divide...
4/11 =.3636
multiply by 100 to convert to a percentage ( move decimal to the right 2 places).
.3636 = 36.36%
There is a 36.36% chance that a boys name is drawn.
The quotient is 18.5, so that means it is between 17 and 20
