Answer:
The equation that can be used to determine m, the number of minutes it will take the helicopter to reach the hospital is
.
Step-by-step explanation:
We are given that a medical rescue helicopter is flying at an average speed of 172 miles per hour toward its base hospital. At 2:42 p.m., the helicopter is 80 miles from the hospital.
As we know that the Distance-Speed-Time formula is given by;
![\text{Distance} = \text{Speed}\times \text{Time}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%7D%20%3D%20%5Ctext%7BSpeed%7D%5Ctimes%20%5Ctext%7BTime%7D)
Here, Distance = 80 miles
Speed = 172 miles per hour
Time = m (the number of minutes)
Firstly, as we can see that the speed is in miles per hour but the time is in minutes, so we will convert the time in hours, i,e;
Time =
So, ![\text{Distance} = \text{Speed}\times \text{Time}](https://tex.z-dn.net/?f=%5Ctext%7BDistance%7D%20%3D%20%5Ctext%7BSpeed%7D%5Ctimes%20%5Ctext%7BTime%7D)
![\text{m} = \frac{80 \times 60}{172}](https://tex.z-dn.net/?f=%5Ctext%7Bm%7D%20%3D%20%5Cfrac%7B80%20%5Ctimes%2060%7D%7B172%7D)
m = 27.91 ≈ 28 minutes.
Hence, it will take 28 minutes for the helicopter to reach the hospital.
Answer:
Solution:
Mouse ran 360 cm straight course race in 9 seconds.
We need to find the rate or speed of mouse
We know the speed formula is distance covered by given time.
Where,
Distance = 360 cm
Time = 9 seconds
speed
Speed=40 cm/s
Mouse ran with speed 40 cm/s
Volume of a cylinder is pi*r^2*h so we get
3.14*4.5^2*10=636.2cubic feet or ft^3
