Using the following formula, where D is distance, R is rate of speed, and T is time, solve the problem “At 2:30 p. m. Shelly leaves her house and drives at an average speed of 55 mph to her sister’s house. If she arrives at 6:30 p. m. how far away is her sister’s house?”

220 miles

Step-by-step explanation:

t = 6:30 - 2:30 = 4 hours

r = 55miles/hr

d = rt

d = 55miles/hr * 4hr

d = 220 miles

220 miles

Step-by-step explanation:

D = R x T

D = 55 x 4 = 220 miles

i dont understand the question? ?

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
