Question

The function d(x)=1375-110x represents the distance (in miles) a high speed train is from its destination after x hours.

Answer 1

Answer:

12.5 hours

Step-by-step explanation:

The function d(x) = 1375 -110x represents the distance in miles a high-speed train is from its destination after x hours of travel.

So, when the train reaches its destination then d(x) will become zero miles.

Therefore, 0 = 1375 - 110x

⇒ x = 12.5 hours.

So, the train will travel 12.5 hours to reach its destination. ( Answer )
