Vinnie drives his car 210 miles and has an average of a certain speed. If the average speed had been 3mph more, he could have tr
Pachacha [2.7K]

Answer:

35 mph

Step-by-step explanation:

time = distance / speed

210 miles and has an average of a certain speed

t = 210 / s

If the average speed had been 3mph more, he could have traveled 228 miles in the same length of time

t = 228 / (s + 3)

Set equal

210 / s = 228 / (s + 3)

Cross multiply

210s + 630 = 228s

Subtract 210s from both sides

630 = 18s

Divie both sides by 18

35 = s

35 mph

A car travels at a constant speed of 60 miles per hour. The distance, d, the car travels in miles is a function of time, t, in h
scZoUnD [109]

The equation of distance traveled by the car is d(t) = 60 · t, for t ≥ 0.

<h3>What is the equation of the distance travelled by a car?</h3>

In accordance with the statement, car travels in a <em>straight</em> line at <em>constant</em> speed. The distance traveled (d), in miles, is equal to the product of the speed (v), in miles per hour, and time (t), in hours:

d(t) = v · t     (1)

If we know that v = 60 mi/h, then the equation of distance traveled by the car is d(t) = 60 · t, for t ≥ 0.

<h3>Remark</h3>

The statement is incomplete and complete form cannot be found. Then, we decided to complete the statement by asking for the equation that describes the distance of the car.

Kruka [31]

Complete question :

a ladder 5 meters long is leaning against a wall. the base of the ladder is sliding away from the wall at a rate of 1 meter per second. how fast is the top of the ladder sliding down the wall at the instant when the base is 4 meters from the wall?

Answer:

-4/3 m/s

Step-by-step explanation:

Using Pythagoras :

a² = x² + c²

5² = x² + y² - - - (1)

The horizontal distance x with respect to time t = 1m/sec

dx/dt = 1m/sec

To obtain the vertical height 'y' with respect to time t when x = 4

5² = x² + y²

Wen x = 4

5² = 4² + y²

25 = 16 + y²

y =√(25 - 16)

y = 3

Differentiate (1) with respect to t

x² + y² = 25 - ---- - (1)

2x * dx /dt + 2y dy/dt = 0

dx/dt = 1

x = 4.

y = 3

2(4)(1) + 2(3) * dy/dt = 0

8 + 6dy/dt = 0

6 dy/dt = - 8

dy/dt = - 8/6

dy/dt = - 4/3
