Time equal to distance divided by the speed. In this question, Sarah need 2 hours and 40 minutes(or 160 minutes) to loop around the north part of Lake Washington. The time for the same distance cutted by 6 minutes if the speed increased by 1km/h. The calculation would be:
time= distance/speed
distance= time*speed=
distance1= distance2
time1*speed1= time2*speed2
160min*speed1= (160min-6min)*(speed1+1km/h)
160 speed1= 154 speed1 + 154km/h
160 speed1- 154 speed1 = 154km/h
speed1= 154km/h /6= 25.67km/h
Answer:
w=2 3/4
Step-by-step explanation:
Answer:
7625597484987 ways
Step-by-step explanation:
Given the following :
Number of ball(k) = 9
Number of bins (n) = 27
How many different ways are there to distribute these 9 balls among the 27 bins.
Here, the balls have different labels (1 to 9)
The bins are also distinguishable, therefore each ball can go into any of the 27 distinct bins.
Therefore, the different ways are there to distribute these 9 balls among the 27 bins equals = n^k
27^9 = 7625597484987 ways.
