Answer:
Donna traveled for 8 hours at 90 mph
Maple traveled for 4 hours at 50 mph
Step-by-step explanation:
The velocity at which each person traveled is given by the distance traveled divided by the time spent (t). From the information given, the following expressions can be written
Therefore, Donna traveled for 8 hours at 90 mph and Maple traveled for 4 hours at 50 mph.
We are given
Alexio has 100 cards numbered 1-100, inclusive, and places them in a box
so, total number of outcomes =100
now, we have chooses a card from the box at random
that is multiple of 2 , 3 or 5
so, firstly, we will find number of possible outcomes that is multiple of 2 , 3 or 5
Firstly, we will find which can't be multiple of 2, 3 and 5
that will be
={ 1, 7,11,13,17,19 , 23 , 29 , 31 , 37 , 41, 43 , 47 , 49 , 53, 59 , 61 , 67, 71, 77, 79, 83, 89 , 91 , 97 }
so,
number of possible outcomes =100-25=75
now, we can find probability
probability = (number of possible outcomes )/(total number of outcomes)
now, we can plug values
and we get
