Answer:
His average speed is 4.75 m/s
Step-by-step explanation:
Here, we are interested in calculating the average speed of the boy.
At time t = 4 seconds, total distance traveled = 6 meters
The average speed here is distance/time = 6/4 = 1.5 m/s
Now at time 30 7 seconds , he has rolled 30 meters
What this actually means is that for the next 3 seconds after the initial 4 seconds, he rolled a total distance of 30-6 = 24 meters. Hence, he rolled 24 meters in the next three seconds
So mathematically, his average speed for the second part of the rolling is 24/3 = 8 meters per second
Conclusively therefore , his average speed will be (1.5 + 8)/2 = 9.5/2 = 4.75 meters per second
Answer:
When I solved it I got (A)
Step-by-step explanation:
Answer:
y= 4x + 11 and no.
Step-by-step explanation:
Because you spent the 11 dollars extra and rode the rides meanwhile your friend only went on the rides. If (x) equals the amount of rides and (y) means the total amount. Then your friends equation with be y= 4x. But, you already spent 11 dollars additionally so therefore your equation with be y=4x + 11.
I hope this helped.
Friend y=4x
You y=4x + 11
