Answer: 60miles/hours
Step-by-step explanation:
From the question, a bus travels the 240 miles from Boston to New York and the bus departs at 11:00 a.m. and arrives in New York at 3:00 p.m. The time taken by the bus is (3:00pm - 11:00am) = 4 hours.
Average speed = Distance/Time
Average speed =240miles/4 hours
Average speed= 60miles/hours
The the average speed of this bus is 60miles/hour.
<span>5x + 2y = 20
put x=0.3
5(0.3) + 2y = 20
2y = 20-1.5
2y = 18.5
y = 9.25

Answer:
Doreen is within the radius of the tower (at the limit).
Step-by-step explanation:
(Assuming that the first 15 miles is East or West)
We can calculate Doreen's distance to the tower using Pythagoras theorem, as these coordinates form a triangle with a 90 degrees angle:
Distance^2 = 15^2 + 8^2
Distance^2 = 225+64
Distance^2 = 289
Distance = 17 miles
Doreen is at 17 miles from the tower, and the tower range is 17 miles, so Doreen is within the radius of the tower (at the limit).
