Two people are driving to work at different constant speeds. The graph below shows the distance traveled over time by driver 1.

Luden [163]

Answer:

5 mph

Step-by-sep explanation:

To find of out the difference between the speed of the two drivers in miles per hour (not in miles per minute), first, calculate the unit rate or speed of driver 1 using the graph, and driver 2 using the table given.

Unit rate/speed = distance travelled/time = y/x.

Speed of Driver 1/unit rate:

The graph shows 1.5 miles (y) is travelled in 2 minutes (x).

Convert the 2 minutes to hour, you will have:

$\frac{2}{60} = \frac{1}{30} hr$

Speed in mph = $\frac{y}{x} = \frac{1.5}{\frac{1}{30}} = 1.5*\frac{30}{1} = 45$

Speed of Driver 1 in mph = 45 mph

Speed of Driver 2/unit rate:

The table shows 2.5 miles (y) is travelled in 3 minutes (x).

Convert the 3 minutes to hour, you will have:

$\frac{3}{60} = \frac{1}{20} hr$

Speed in mph = $\frac{y}{x} = \frac{2.5}{\frac{1}{20}} = 2.5*\frac{20}{1} = 50$

Speed of Driver 2 in mph = 50 mph

Difference between the speed of the two drivers = 50 - 45 = 5 mph

Solve 5.4 = n/-0.9 Answers: a. -4.86 b. -48.6 c. 48.6 d. 4.86

ZanzabumX [31]

Answer: 4.86

Step-by-step explanation: Since n is being divide by 0.9, to get n by itself, we need to multiply by 0.9 on both sides of the equation.

On the right side of the equation, the 0.9's cancel and we have n. On the left side of the equation, we have 0.9 × 5.4 which is 4.86.

Therefore, 4.86 = n.

AB and CD are parallel. EF is the translation of AB. Is EF parallel to CD? Justify. What does this prove about the effect of tra

fenix001 [56]

No because EF is a translation and it cannot be parallel to CD. If AB and CD are parallel and EF is the translation then it would not work. If it was a reflection then it would be parallel.
