Respuesta :
Well if you divide 30 by 10 then multiply by 4 you get 12 minutes.
Do the same for 45,
45 divided by 10 = 4.5 then multiply by 4 = 18
The number of miles the train will travel at the same speed is 18 miles
From the question,
We are to determine the number of miles the train travel in 12 minutes
From the question
It takes an express train 30 minutes to travel 45 miles
First, we will determine the speed
From the formula
[tex]Speed = \frac{Distance}{Time}[/tex]
Distance = 45 miles
Time = 30 minutes
∴ [tex]Speed = \frac{45}{30}[/tex]
Speed = 1.5 miles/mins
Now,
For the number of miles the train travel in 12 minutes
Time = 12 minutes
Using the formula
Distance = Speed × Time
∴ Distance = 1.5 × 12
Distance = 18 miles
Hence, the number of miles the train will travel at the same speed is 18 miles
