A map shows a section of Interstate 94 that forms a straight line. A family plans to drive 72 miles on Interstate 94 from St Paul, MN to Elk Mound, WI. They drive for 20 miles, and then decide they will stop halfway through their trip to eat. How much farther do they need to drive before they stop for dinner?

16 miles

Step-by-step explanation:

Given that:

Total distance of the trip = 72 miles

They have decided to stop half way their trip i.e. they will stop at a distance miles from the starting point.

Also, given that they have already traveled for 20 miles.

To find:

How much farther do they need to drive before they stop for dinner?

Solution:

Distance already covered = 20 miles

Distance to be covered before stopping for dinner = 36 miles

Distance to be covered more = Total distance to be covered before stopping - Distance already covered

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
