Two cyclists, 80 miles apart, start riding toward each other at the same time. One cycles 3 times as fast as the other. If they

vivado [14]

The speed of the faster cyclist will be 30 miles/hour.

Explanation

One cyclist is 3 times as fast as the other.

Lets assume that the speed of the slower cyclist is $x$ miles/hour.

So, the speed of the faster cyclist will be: $3x$ miles/hour.

They start riding toward each other at the same time and meet 2 hours later.

We know that, $Distance= speed*time$

So, the distance traveled by slower cyclist in 2 hours $= (x*2)miles= 2x$ miles and the distance traveled by faster cyclist $=(3x*2) miles = 6x$ miles.

Given that, they were 80 miles apart at the starting. So, the equation will be.....

$2x+6x=80\\ \\ 8x=80\\ \\ x=10$

So, the speed of the faster cyclist will be: (3×10)= 30 miles/hour.

List the descriptors used to interpret a scatterplot and provide a brief explanation for each

Monica [59]

The descriptors used to interpret a scatterplot are strength, association and trends. The strength determines how closely the dots fall to the line, the association is the general direction in which the dots fall, and the trend or shape lets one know if the graph is linear or non-linear.
