Question

harper rides her bike 15 miles in 3 hours if she rides at a constant speed, select the answers below that equivalent ratios to the speed she rides. select all ratios that are equivalent

Answer 1

First let's find her speed, dividing the number of miles by the amount of time:

`\text{speed}=(15)/(3)=5\text{ mph}`

Now, let's calculate the speed for each option:

1) 20 miles in 4 hours

`\text{speed}=(20)/(4)=5\text{ mph}`

2) 25 miles in 6 hours

`\text{speed}=(25)/(6)=4.17\text{ mph}`

3) 10 miles in 3 hours

`\text{speed}=(10)/(3)=3.33\text{ mph}`

4) 5 miles in 1 hour

`\text{speed}=(5)/(1)=5\text{ mph}`

So the correct options are 1) and 4).
