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 100m ?

A. 65s
B. 3500s
C. 2.9s
D. 5.9s

Answer 1

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

Answer 2

Answer:

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.

$s=\dfrac{d}{t}$

$t=\dfrac{d}{s}$

$t=\dfrac{100\ m}{35\ m/s}$

t = 2.85

or

t = 2.9 s

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