You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.
90/60 = 1.5
90 minutes = 1.5 hours
speed = distance/time = (105 miles)/(1.5 hours) = 70 mph

Step-by-step explanation:
For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.
If the number of trials is changed, the experimental probability also changes.
If the number of trials is changed, the predicted number of outcomes also changes.
If the number of trials is changed, the number of experimental outcomes also changes.

Answer:
25/10
Step-by-step explanation:
Make the fractions improper by multiplying the whole number by the denominator and then adding the numerator (if this makes sense).
This makes 5x10=50+3=53/10
Do the same for the second fraction. 2x5=10+4=14/5
Then make the denominators the same, and in this case all you need to do is multiply both sides of 14/5 by 2, so that makes 28/10.
Now, just take it away.
53/10-28/10=25/10, which can be then simplified into 2 1/2 or 5/2.
