2. rian runs a road race at an average speed of 6 miles per hour. rayna runs the same race at an average speed of
11 kilometers per hour
who moving is faster? explain or show your reasoning
note: there are about 8 kilometers in 5 miles.

Rayna.

Step-by-step explanation:

Rian: 6 miles per hour

Rayna: 11 kilometers per hour

8 kilometers=5 miles

5/8=x/11

cross product

8*x=5*11

8x=55

x=55/8

Rayna: 55/8 miles per hour

55/8>6 since 55/8=6.875.

Therefore, Rayna moves faster.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

i believe that the slope of the line is -5
