Dan bikes 10 miles in 50 minutes.at this rate , how far can she bike in 90 minutes
jarptica [38.1K]

Answer:

Dana would go 18 miles in 90 minutes because she is going a mile for every five minutes, so if she bikes for another forty minutes she will have biked 8 miles. This means that you would multiply 8 miles (remember its a mile per 5 minutes) by five minutes and that would give you forty. Then just add that on to the 50 minutes she has already biked.

or do it this way

To get the answer you need to find out how many miles she bikes in 10minutes.

Divide 50minutes by 10 you get 5. Now you divide 10(miles) by 5 and you get 2. So it means that in 10minutes she bikes 2miles. Now you need to know how many miles she bikes in 90minutes so if she bikes 2 in 10 then because 90:10=9 you do 2*9=18. She can bike 18miles in 90minutes. :))

Choose the graph that correctly corresponds to the equation y=4
Lera25 [3.4K]

Graph 1 is y = 4.

You can tell this because no matter what point you pick on that line, the ordered pair will contain the number 4 for y. You can also tell because y = a number graphs are always horizontal lines.
