Question

A racing car can complete an 700 m long lap in 14 s. What is the speed of the car?

Answer 1

Answer:

The answer is 50 m/s

Step-by-step explanation:

The speed of an object can be found by using the formula

$v = \frac{d}{t}$

where

v is the speed

d is the distance

t is the time

From the question

d = 700 m

t = 14 s

We have

$v = \frac{700}{14}$

We have the final answer as

50 m/s

Hope this helps you

Answer 2

Answer:

$\boxed {\tt 50 \ m/s}$

Step-by-step explanation:

To find the speed, divide the distance by the time. We can use the following formula:

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

The racing car completed a 700 meter lap in 14 seconds. So, the distance is 700 meters and the time is 14 seconds.

$d= 700 \ m \\t= 14 \ s$

Substitute the values into the speed formula.

$s=\frac{700 \ m }{14 \ s}$

Divide.

$s= 50 \ m/s$

The speed of the racing car is 50 meters per second
