With a short time remaining in the day a delivery driver has to make deliveries at 5 locations among the 6 locations remaining.
nika2105 [10]
The delivery driver has to make deliveries at 5 locations <span>among the 6 locations. </span>This means the order of the probability is important because the route he will take from A to B is different with A to C.
So, you need to use permutation for this problem. The calculation would be:
6P5= 6!/ (6-5)!= 720 different routes

Simplify 194/120 the answer will be ? you answer
Advocard [28]
Note: 2*2 means 2 times 2
find the factors since
4/8=1/2 because 1/2 times 4/4=4/8
194=2*97
120=2*2*2*3*5
the common number is 2 so divide both by 2
97/60 is the simplest form
in improper fraction form it is
97-60=37
1 37/60

Ed is on a road trip he has already traveled 201 miles and is driving at a rate of 61 mph the equation could be used to find how
Bas_tet [7]

Answer:

Ed has traveled for 3 hours and 17 minutes, and has 2 hours and 28 minutes left to travel.

Step-by-step explanation:

Given that Ed is on a road trip and he has already traveled 201 miles and is driving at a rate of 61 mph, the equation could be used to find how many hours he has traveled and how many and has left in his road trip traveling 697 total miles is the next:

201/61 = 3.29

100 = 60

29 = X

29 x 60/100 = X

29 x 0.6 = X

17.4 = X

So, Ed has traveled for 3 hours and 17 minutes.

697 - 201 = 496

496/201 = 2.46

100 = 60

46 = 0

46 x 0.6 = X

27.6 = X

Thus, he has 2 hours and 28 minutes to travel.
