The average speed of the truck is calculated by dividing the total distance traveled in a span of the total time given. From the given above, the total distance traveled is
total distance = 203 mi + 243 mi = 446 mi
and the total time it took for the whole trip is
total time = 3.5 h + 4.5 h = 8 h
The average speed is therefore,
average speed = 446 mi/8 h = 55.75 mi/h
Thus, the answer is letter A.
Answer:
Step-by-step explanation:
<u>Let the capacity of tank is x</u>
- 1/5x + 9 = 7/10x
- 2/10x + 9 = 7/10x
- 5/10x = 9
- 1/2x = 9
- x = 18 gallons
Answer:
You can also use a dot plot to identify the shape of a distribution. All the dots are about the same height. A uniform distribution is also symmetric. The data on the right of the distribution are approximately a mirror image of the data on the left of the distribution.
