Answer:
Step-by-step explanation:
let after t hrs they are 24 miles apart.
48t+36t=24
84t=24
t=24/84=2/7 hrs
=2/7×60=120/7 minutes =17+1/7
=17minutes +1/7×60sec
=17 minutes +60/7 sec
=17 min 8 4/7 sec
10.00+00.17 =10.27
Time≈10.27 a.m.
The product of the values -2/7 and -3/4 is 3/14
- Cassie's fraction =
- Amy's fraction =
<u>The multiplication expression which relates Cassie's fraction with Amy's can be written thus</u> :
- Cassie's fraction × Amy's fraction
- The negative cancels out after multiplying both values.
Therefore, the multiplication result of the two fractional values is

Coeficients are: a = 3; b = 4; c = 2;
Because
