Question

A car travels 120 miles in 3 hours ( with a constant speed). How far will it take to travel 200 miles?

Answer 1

5 hours

explanation:

120 miles in 3 hours

therefore,

40 Miles per hour.

40: 1

200: x

40 x x / 200 x 1

40 x x = 200 x 1

x= 200 / 40

x= 5

therefore,

5 hours

Answer 2

Answer:

Time taken by car to travel 200 miles = 5 hours

Step-by-step explanation:

Given :

Car travel distance in 3 hours = 120 miles

To find :

Time taken by car to travel 200 miles

Concept :

First find the speed of the car km/hr .

So , to find the speed use this formula -:

$\boxed{\sf{S=\dfrac{D}{T}}}$

Where,

S = Speed

D = Distance

T = Time

After that to find the times use this formula -:

$\boxed{\sf{T=\dfrac{D}{S}}}$

Solution :

First speed -:

$\Rightarrow\sf{S=\dfrac{120miles}{3hr}}$

$\Rightarrow\sf{S=40mile/hr}$

So , the speed of the car is 40 miles per hour .

Now , distance -:

$\Rightarrow\sf{T=\dfrac{200miles}{40miles/hr}}$

$\Rightarrow\sf{T=5hr}$

So , the times taken by the car to travel 200 miles is 5 hours .
