ladessa [460]

Answer:

The area of the country is 17 square miles

Step-by-step explanation:

Area of country = Population of country/population density of country

Area of country = 4288/257

Area of country = 16.68 square mile

Shania drove on the interstate for 310 miles without stopping. If she traveled at a constant rate and the trip took her 5 hours,
sp2606 [1]

Answer:

62 miles per hour/62 mph

Step-by-step explanation:

Shania drives at a CONSTANT rate, which means in the 5 hours it took her to drive, each hour she drove the same amount.

So we need to do 310 miles in 5 hours, which is:

310/5

Solving this, we get:

62

The answer is 62 miles per hour.

Happy learning!
