A car traveled a distance of D = 199 km (kilometers) for T = 4.2 hours at a constant rate. Use the formula D = R · T
to find the speed (R) of the car in km per hour. Round your answer to the nearest tenth.

47.4 not rounded 47.38

Step-by-step explanation:

You divide 199 by 4.2 and get 47.4 and then you can multiply 47.38x4.2 and will get you 199

Step-by-step explanation:

199 =R×4.2

R= 199÷2

R= 47.38km

nearest tenth is 47.4

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
