Answer:
24 seconds
Step-by-step explanation:
a truck is traveling at a constant rate of 90 kilometers per hour
1 kilometer = 1000 meters
90 kilometer = 90000 meters
1 hour = 3600 seconds
90 km per hour is 90000 meters per hour
convert it in to meters per second
[tex]\frac{90000}{3600} =25[/tex]
Time = distance over speed
speed= 25 m per second
distance = 600 meters
[tex]time =\frac{600}{25} =24[/tex]
