Answer:

250 miles

Step-by-step explanation:

Your formula is d=r(t)

d=distance r=speed t=time

In this equation it is asking you how far will you travel if your speed is 50 miles per hour, and the time is 5 hours.

So, using the equation above insert the known numbers and it should look like this: d=50(5) ( distance is unknown / speed is 50 / time is 5 )

Now you can find the distance. All you do is multiply 50 times 5 which equals 250.

So the correct answer is C. 250 miles

azamat

Answer:

The total weight of his purchase is 1.08 pounds
