The time it takes to cover the distance between two cities by car varies inversely with the speed of the car. the trip takes 13 hours for a car moving at 68 mph. what is the speed of a car that makes the trip in 17 hours?

Alright, lets get started.

The trip takes 13 hours for a car moving at 68 mph.

We could find the distance between both cities with help of this.

Distance = time * speed

Distance = 13 * 68 = 884 miles

Means the distance between both cities = 884 miles

Now if the trip takes 17 hours, we need to find new speed.

For finding this new speed, one thing that not changed is, distance between two cities that is 884 miles.

Speed = distance / time

Speed = 884 / 17

Speed = 52 miles / hr

Hence, the speed of the car is 52 miles / hr : Answer

Hope it will help :)

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
