A cart travels 3.6 meters in 1.8 seconds. What is the average speed of the cart?
Lady_Fox [76]
For solving this we need the change in distance and the change in time.  You said that the change in time is 1.8 seconds and the change in distance is 3.6 meters.  ( This is assuming it started at 0 meters and started at 0 seconds )

Since the starting was 0,0 we can toss them out as they add no value.  Now since speed is labeled (in this case) m/s, we divide how many meters it traveled over how many seconds it took to travel it.

3.6 / 1.8 = 2

The average speed of the cart is 2 m/s

tino4ka555 [31]

Answer:

See below.

Step-by-step explanation:

For item 2:  

The Net Price Rate = 276 / 460 = 0.60 = 60 % (answer).

Item 3: Net Price Rate =  3247 * 100 / 3820 = 85% (answer).

Item 4 Net Price Rate =  675.11 / * 100 / 987 =  68.4%. (answer).

Item 5 Item's Net Price = 987 * 0.675 = $666.23 (answer).

Item 7 Net price Rate =  2945* 100 / 4750 = 62%. (answer).

Item 8: First find the list place $x:

0.90* 0.80 * 0.70x  = 252   ( the 0.90 , 0.80 and 0.70 come from 100 - 10% = 1 - 0.10 = 0.90  and so on)

0.504 x = 252

x = $500

Answer is List Price = $500 and Net Price Rate = 50.4%.

Item 10  List price =  2890.65 / 0.35 = $8259. (answer)
