The answer you are looking for is 22 mph.
Solution:
s=speed
d=distance
t=time
Setting up the formula for the speed of an object with distance and time:
s=d/t
Substituting the given values,
s=88 miles/4 hours
So, therefore, the final answer is 22 mph.
I hope this helped answer your question for you. Good day to you.
Explanation:
It is given that,
Frequency of diagnostic ultrasound, f = 3.82 MHz = 3820 Hz
The speed of the sound in air, v = 343 m/s
(a) We need to find the wavelength in air of such a sound wave. Let it is given by λ₁
i.e. 
(b) If the speed of sound in tissue is 1650 m/s .
Hence, this is the required solution.
Answer: (5/6) m/s
Explanation:
Distance = 100m
Time taken = 2 min
= 2 × 60 s
= 120 s
Speed = ?
Now,
Speed = distance / time taken
Speed = 100 / 120
Speed = (5/6) m/s
Answer:
You will cover a distance of 1569.06 metres. Or you could round down to 1,569m.
Explanation:
20.7*75.8=1563.06
use the formula
v= u+ at
v is final velocity , u is initial velocity , a is acceleration and t is time
put the values
20 = 0+ a×5
a = 4 m/s²
