Answer:
Average Speed to complete the journey = 80 km/h
Step-by-step explanation:
Given,
The distance between Sydney and Goulburn = 200 kilometer.
Time to complete the journey = 2 hour 30 minutes
Converting the time into minutes -
2 hour 30 minutes
= (2 x 60) minutes + 30 minutes
= 120 minutes + 30 minutes
= 150 minutes
We know, to determine average speed, we have to divide the distance by time.
Therefore, Speed = ![\frac{Distance}{Time}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%7D%7BTime%7D)
Speed = ![\frac{200 km}{150 minutes}](https://tex.z-dn.net/?f=%5Cfrac%7B200%20km%7D%7B150%20minutes%7D)
Speed = 1.33 km/minutes
Speed = (1.33 km x 60) km/hour (To convert it to hour, we have to multiply by 60)
Average Speed per hour = 80 km/h
The answer would be 5 times 6 which would give you the answer of 30 car trucks
1. 3(p+q)=p
3p+3q=p; 3p-p=3q; 2p=q so p=q/2
2. 4a=2b-7
2b=4a+7 so b=(4a+7)/2
when a=3 , b=(12+7)/2=19/2=9.5
3. d=rt; r=d/t
4.( 2x15)+(2xwidth)=90
2x width=90-30
width =60/2=30
