Question:

The equation for distance is d = st. if a car has a speed of 35 m/s, how long will it take to go 100 m? a. 3500 s b. 2.9 s c. 5.9 s d. 65 s

Answers

d = st

100 = 35t

35t = 100

35t/35  =  100/35

t =  20/7  or 2.9 s

100 will be your d and 35 is your s, now you can put them into the formula, then solve for t.

Time, t = 2.9 s

Explanation:

It is given that,

Speed of the car, s = 35 m/s

Distance covered, d = 100 m

We have to find the time taken by the car to go 100 m. Speed of an object is given by total distance divided by total time taken.

[tex]s=\dfrac{d}{t}[/tex]

[tex]t=\dfrac{d}{s}[/tex]

[tex]t=\dfrac{100\ m}{35\ m/s}[/tex]

t = 2.85

or

t = 2.9 s

Hence, the time taken by the car to go 100 m is 2.9 seconds

D = 100
s = 35

d = st ⇒ t = d/s

Solve for t.

The answer is not B!

I thinks that the answer is B.3500 s

they should be similar or the same
