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: 1.625
Step-by-step explanation:
u need to simplify the fraction then u subtract
Uhhh... I think it’s D but that could be wrong
Answer:
-1/2
Step-by-step explanation:
the slope is difference in y over difference in x, so (-3-(-1))/(2-(-2)): aka -2/4 aka -0.5 or -1/2
plug in the points to find the y intercept,
the equation of the line is y = -0.5x -2 incase you need it.
