Question

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

Answer 1

The answer is 50 m/s

Explanation:

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

`v = (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 = (700)/(14) \\`

We have the final answer as

50 m/s

Hope this helps you

Answer 2

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

Explanation:

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

`s=(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=(700 \ m )/(14 \ s)`

Divide.

`s= 50 \ m/s`

The speed of the racing car is 50 meters per second
