Aneesha travels at a rate of 50miles per hour. morris is traveling 3 feet per second less than aneesha. which is the best estimate of the speed morris is traveling? 1 mile=5,280 feet a. 45 miles per hour b. 46 miles per hour c. 47 miles d. 48 miles per hour

Morris is traveling at 48 mph.

Step-by-step explanation:

You may know the identity 88 ft/sec = 60 mph.  Using this makes the solution of this problem relatively easy.

First, we'll convert 50 mph to ft/sec:

50 mph           88 ft/sec

* = 73.3333 ft/sec

1 sec                 60 mph

So, Aneesha is traveling at 73.3333 ft/sec.  Morris is traveling 3 ft/sec slower, which works out to  70.3333 ft/sec.  We have to convert this back to miles per hour:

70.3333 ft/sec        60 mph

* = 47.95 mph, or 48 mph (Answer D)

          1                     88 ft/sec

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
