Answer: option B is the correct answer.
Step-by-step explanation:
Susan drove at an average speed of 30 miles per hour for the first 30 miles of a trip.
Time = distance/speed
This means that time spent by Susan in travelling the first 30 miles would be
Time = 30/30 = 1 hour
He travelled at an average speed of 60 miles per hour for the remaining 30 miles of the trip.
Time = 30/60 = 0.5 hours
Total distance travelled is 30 + 30 = 60 miles.
Total time spent = 1 + 0.5 = 1.5 hours
Speed = distance/time
Average speed = 60/1.5 = 40 miles per hour.

Answer:
Dylan will not have enough money. He needs $22.65 but only has $22.50
Step-by-step explanation:
If Dylan's mom replaces each dime with a quarter, then Dylan will have 90 quarters.
1 Quarter = $0.25
90 x .25 = $22.50
The game costs $20.98 plus 8% sales tax
So 20.98 x .08 = <em>$</em><em>1.6784</em>
20.98 + 1.6784 = $22.65
<em>Dylan</em><em> </em><em>will</em><em> </em><em>not</em><em> </em><em>have</em><em> </em><em>enough</em><em> </em><em>money</em><em> </em><em>because</em><em> </em><em>he</em><em> </em><em>only</em><em> </em><em>has</em><em> </em><em>$</em><em>2</em><em>2</em><em>.</em><em>5</em><em>0</em><em> </em><em>when</em><em> </em><em>he</em><em> </em><em>needs</em><em> </em><em>$</em><em>2</em><em>2</em><em>.</em><em>6</em><em>5</em>
Answer:
x=1/2, x=5
Step-by-step explanation:
2x^2-11x+5=0
Factor them
(x-0.5)(x-5)
x=0.5 or 1/2
x=5
