Question

A car covers 6 km in 4 minutes. If it travels same speed how much distance will it cover in 2 hours​

Answer 1

Step-by-step explanation:

speed= 6 km per 4 minutes

time = 2 hours=120 minutes

distance=speed ^ time

6/4 km/min^ 120minutes

=180 km

Answer 2

FORUMULA :

$\sf{distance = speed \times time}$

$\sf{speed = \dfrac{distance}{time} }$

STEP BY STEP EXPLANATION :

We know that,

$\sf{speed = \dfrac{distance}{time} }$

so,

$\sf{speed \: of\: car = \dfrac{6}{4} = \dfrac{3}{2} = 1.5}$

So the speed of car at 4 min is 3 ÷ 2 km/min.

we want to find for 1 min,

$\sf{1 \min = \dfrac{1.5}{4} \: km \:/ min}$

so at 2 hours is ( 60 × 2 = 120 min)

$\sf{\dfrac{1.5}{4} \times120=45 \: km/min}$

$\sf{\therefore \: The \: speed \: of \: car \: at \: 2 \: hours \: is \: 45 \: km/min}$
