Answer:
Speed of a= 21 miles/hr
r = Speed of b= 7 miles/hr
Speed of a = 3r
Step-by-step explanation:
The cyclist are 112 miles apart
Time traveled by two = 4 hours
Speed of a = 3 * speed of b
If a cylcles 3 times More than b, then a will cover 3*distance of b
But speed = distance/time
Time = 4hours
Total distance=112
a = 3b
3b + b = 112
4b = 112
b = 112/4
b = 28 miles
a = 3b
a = 3*28
a = 84 Miles
They bought traveled 4 hours
Speed of a = 84miles/4 hours
Speed of a= 21 miles/hr
Speed of b = 28miles/4 hours
Speed of b = 7 miles/hr
Answer:
<h2><u><em>
A) -1</em></u></h2><h2><u><em>
B) -1.5 or -3/2</em></u></h2>
Step-by-step explanation:
Solve 3-4 and (1⁄2)-2
3 - 4, 4 is greater than 3, so the result is negative (-1)
3 - 4 = -1
-----------------
1/2 is equal to 0.5, also here 2 is larger and we will have a negative result (-1.5 or -3/2)
1/2 - 2 =
0.5 - 2 = -1.5 or -3/2
Answer:
The answer is

Step-by-step explanation:

By the way can find y
If to a whole number, you'd round to 28. If for a tenth, it'd go to 26.8, if for a hundredth, it'd go to 26.78.
Hope this helps!
