Answer: 2 2/5 distance
Step-by-step explanation:
You know 1/4 of an hour you travel of 3/5 of distance, so let’s set an proportion: 1/4 hr = 3/5 of distance, multiply 4 on both sides, and you get 2 2/5 distance. Hope this helps!
The answer to the question is true
Answer:
The Ratios are Proportional
Step-by-step explanation:
Let,
R1 = 48 / 72 ----- (1)
R2 = 6/9 ------ (2)
If we divide right hand side of above equation by 8, we get,

Therefore, it means that, in simplified form, both ratios are same and hence proportional.
R1 : R2 = 6/9 : 6/9
