Brainliest to correct!! Please help :) A truck enters a highway driving 60mph. A car enters the highway at the same place 5 min later and drives 71 mph in the same direction. From the time the car enters the highway, how long will it take to pass the truck?

It will take ___ minutes?

The more accurate value is 27.272727... where the "27"s go on forever.

The answer in fraction form is 300/11. I prefer the approximate form better since it's easier to conceptualize "27 minutes" as opposed to "300/11 minutes".

Explanation:

x = time it takes the car to pass the truck (in minutes).

The car enters the highway and drives for x minutes until it passes the truck.

The truck is on the highway for 5 extra minutes, since it got a head start, so the truck travels for x+5 minutes until the car passes it.

Everything so far is talking about minutes and not hours. However, the speed values are in miles per hour. So let's convert everything to "miles per minute". To do so, we divide by 60.

I'll leave the fraction as it is. Optionally you can convert to decimal form. Those speeds represent the truck and the car in that order.

The car has these properties

Using the distance = rate*time formula, we then can see that the car travels (71/60)x miles

The truck has these properties

So the truck travels a distance of x+5 miles

The two vehicles must travel the same distance if we want the car to overtake the truck. In other words, the car and truck must be tied for the car to eventually pass the truck.

Truck's Distance = Car's Distance

x+5 = (71/60)x

60(x+5) = 71x

60x+300 = 71x

300 = 71x-60x

300 = 11x

11x = 300

x = 300/11

x = 27.272727 which is approximate. The "27"s go on forever.

Rounding to the nearest whole minute, we get approximately 27 minutes which is the time it takes for the car to pass the truck. This is where we defined the starting point being after the car enters the highway.

you are saying it as if a fact, not a question, but yes, you would be correct? ; )
