A group of students is timed while sprinting 100 meters. Each student’s speed can be found by dividing 100 m by their time. Is each statement true or false?

Select the correct choice for each statement then explain your reasoning.

1. Speed is a function of time.
2. Time is a function of distance.
3. Speed is a function of number of students racing.
4. Time is a function of speed.

Answers

Answer 1

Answer:

The true statements are (a) and (d)

Step-by-step explanation:

(a). Speed is a function of time : As seen from equation (1) Speed of the students varies according to the value of time. So, This a true statement.

(b). Time is a function of distance : Distance is not varying in the equation (1), it is fixed to be 100. So, time is not a function of distance because here the distance is made constant. So, This is false statement.

(c). Speed is a function of number of students racing : Speed is not depending on the number of students racing so sped is independent of the number of the students racing. Therefore, Speed is not a function of number of students racing. This is False statement.

(d). Time is a function of speed : As seen from equation (1) Time of the students varies according to the value of their speed. So, This a true statement.

The true statements are (a) and (d).

Answer 2
The true statement are (a) and (b)

a. How high above the water is the roadway in meters? Round to the nearest hundredth.

The roadway is about ____ meters above the water.



Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.

The length of the bridge is about ____ kilometers.

Answers

a: 60.66 m
b:8.04 km

The roadway is about 60.66 meters above the water.

The length of the bridge is about 8.04 kilometers.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

We have,

The length of the roadway above the water = 199 ft

1 ft = 0.3048 m

Multiply 199 on both sides.

199 ft = 60.66 m

The bridge has a length of 26,372 feet.

1 ft = 0.0003048

Multiply 26372 on both sides.

26372 ft = 26372 x 0.0003048

26372 ft = 8.04 km

Thus,

The roadway in meters is about 60.66 meters above the water.

The length of the bridge in km is about 8.04 kilometers.

Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices

Rosemary needs to maintain 126 mph.

Rosemary needs to maintain 65 mph.

Rosemary needs to maintain 56 mph.

Answers

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

Answer:

56

Step-by-step explanation:

84 / 1.5 = 56
