Answer:
42 miles.
Step-by-step explanation:
It is given that Mr. and Mrs. Rivers left their house at 10:00 a.m. driving in opposite directions.
Speed of Mr. Rivers = 48 mph
Speed of Mrs. Rivers = 36 mph
We need to find the distance between them at 10:30 a.m.
10:30 - 10:00 = 0:30 = 30 minutes = 1/2 = 0.5 hour
Distance covered by Mr. Rivers in half hour = 48 × 0.5 = 24
Distance covered by Mrs. Rivers in half hour = 36 × 0.5 = 18
Total distance covered by both in half hour = 24 + 18 = 42
Therefore, they are 42 miles far from each other at 10:30 a.m.
Answer:
Y = 4
Step-by-step explanation:
<h2>
<em><u>Y </u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>3</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>9</u></em></h2><h2>
<em><u>Y </u></em><em><u>=</u></em><em><u> </u></em><em><u>4</u></em></h2><h2 />
<h2>
<em><u>that's </u></em><em><u>all</u></em></h2>
It would be first 0.86 then it would be 8/9 and the le last one would be 0.9
