24km/2 hours = 12km/1 hour
Answer:
ambulance speed is 30.38 m/s
Explanation:
given data
hear frequency = 510 Hz
pass frequency = 427 Hz
speed of sound = 343 m/s
to find out
ambulance speed
solution
we consider here ambulance speed is v
so when we hear frequency velocity equation will be
510 = 343f / ( 343 - v ) ...........................1
and when ambulance pass velocity equation will be
427 = 343f / ( 343 + v ) ...........................2
so from equation 1 and equation 2
= 510 / 427
= 510 / 427
solve it we get
v = 30.38 m/s
so ambulance speed is 30.38 m/s
The answer is 50 kg plz mark as brainliest
