Question

A car passes through a street 250 metre long in 54 seconds find the speed of car in km /hours

Answer 1

Ans: 16 2/3 km/hr is the solution

Answer 2

The speed of car is $16\dfrac{2}{3}$ km /hours.

Step-by-step explanation:

It is given that a car passes through a street 250 meter long in 54 seconds.

We need to find the speed of car in km /hours.

1000 m = 1 km

60 seconds = 1 minute

60 Minutes = 1 hour

3600 seconds = 1 hour

Using these conversion we get

250 meter = 1/4 km

54 seconds = $\dfrac{54}{3600}=\dfrac{3}{200}$ hour.

Formula for speed is

$Speed=\dfrac{distance}{time}$

$Speed=\dfrac{\frac{1}{4}}{\frac{3}{200}}$

$Speed=\dfrac{1}{4}\times \dfrac{200}{3}$

$Speed=\dfrac{50}{3}$

$Speed=16\dfrac{2}{3}$

Therefore, the speed of car is $16\dfrac{2}{3}$ km /hours.
