Answer:
The truck's speed is 4.04 m/s.
Explanation:
Given that,
Emit frequency = 600 Hz
Beat = 7.00 beat/sec
We need to calculate the truck's speed
Using formula of speed

Where, v = speed of sound
Put the value into the formula



Hence, The truck's speed is 4.04 m/s.

Answer:
1. Formula = distance/time
 D= 112.0 meters, time =4 secs
 Speed = d/t =112.0/4
 = 28m/s
2.Formula = distance/time
 D= 1/4 x 16093.44 m 
 = 402.35m
 Time = 15secs 
 Speed= d/t
 = 402.35/15
 =26m/s
