Going at the speed he believes he can go, Noah will be able to finish the race in 8.34 hours.
First thing to do is to find out the speed Noah can ride at.
Speed = Distance / Time
The time should be in hours because the proper convention is miles per hour.
= 160 / 60 minutes
= 2.67 hours
Speed = 32 / 2.67
= 11.99 miles per hour
Going at 11.99 miles per hour, he will finish a 100 mile race in:
= Distance / Speed
= 100 / 11.99
= 8.34 hours
In conclusion, Noah will finish the race in 8.34 hours.

Answer:
let time for the race be y minutes
If 32 miles =160 minutes
then 100 miles =y minutes
Cross multiply: (100 miles*160 minutes) = 32 y
y = (100*160)/32 =500
time for the race = 500 minutes
Step-by-step explanation:
floor. How many steps did he climb in 9 seconds?
Answer:
18 steps.
Step-by-step explanation:
He strode 24steps in 12secs, this means that in 1sec, he strode 2steps. So, in 9secs, he strode 18steps

Since triangle M' is the image of triangle M under a dilation, the center of the dilation is: B. B.
In Mathematics and Geometry, a dilation is a type of transformation that is used for altering the dimensions of a geometric figure, but not its shape.
Generally speaking, the coordinates of the pre-image can be dilated by using a scale factor that is centered at the point B by using this mathematical expression:
(x, y) → (k(x - a) + a, k(y - b) + b)
In conclusion, the center of the dilation would be at point B when the three vertex of both triangle M' and triangle M are connected.
