Question

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

Answer 1

120 miles = 3 hrs
1 mile = 3/120 = 1/40
200 miles = 1/40 × 200
= 5 hrs

Answer 2

Answer:

Using formula:

$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$

or

$\text{Time} = \frac{\text{Distance}}{\text{Speed}}$

As per the statement:

A car travels 120 miles in 3 hours(with a constant speed)

⇒Distance = 120 miles and Time = 3 hours

Using formula:

$\text{Speed} = \frac{120}{3}=40$ miles per hour

Now, we have to find how far will it take to travel 200 miles.

⇒Distance = 200 miles.

Using formula for time:

$\text{Time} = \frac{200}{40}=50$ hours

Therefore, 50 hours will it take to travel 200 miles
