Answer:
2.54 miles/hr
2.04 miles/hr
Step-by-step explanation:
<u>Given: </u> Distance between the two towns = 1100 miles
Difference between speeds = miles/hr
Total time when they meet = 240 hours
<u>To find:</u>
Let distance traveled by first group = miles.
Now, the distance traveled by second group = (1100-) miles/hr
The relation between Speed, Time and Distance is given as:
Let speed of first group =
Let speed of second group =
As per question, = +
Now,
Putting value of :
Similarly, putting value of in :
Subtract 6 from both sides (8n=40) then divide 40 by 8 (5) so n=5
Answer:
102
Step-by-step explanation:
You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.
