Answer 1

Answer:

A. 5 ¼ miles

Step-by-step explanation:

t = time

d = distance

15 min. = ¼ hour

1 ½ hr – ¼ hr ≤ t ≤ 1 ½ hr + ¼ hr (subtract & add fractions)

           1 ¼ hr ≤ t ≤ 1 ¾ hr

If   t = 1 ¼ hour

Then     d = 3 miles/hr * 1 ¼ hr (cross hours & multiply)

              d = 3 ¼ miles

If   t = 1 ¾  hour

Then     d = 3 miles/hr * 1 ¾  hr (cross hours & multiply)

              d = 5 ¼ miles

Hope this help! :)
