Answer: her speed on the bicycle is 8 mph
Step-by-step explanation:
Let x represent the speed at which she walks. If she rides 6 mph faster than she can walk, then the speed at which she rides is (x + 6) mph
Distance = speed × time
Eli walk from her house to a friends house in one hour. This means that the distance covered is 1 × x = x miles.
Distance on her bicycle in 15 minutes. Converting 15 minutes to hours, it becomes 15/60 = 0.25 hour. Distance covered while riding is 0.25(x + 6) = 0.25x + 1.5
Since the distance is the same,then
x = 0.25x + 1.5
x - 0.25x = 1.5
0.75x = 1.5
x = 1.5/0.75
x = 2
her speed on the bicycle is
x + 6 = 2 + 6 = 8 mph
Since all the option shows the variation is direct..
I. E y=kx let's take the first one to find the k and as well the relationship
When y=24,x=20
24=k*20
K=24/20
k=6/5
K=1.2....
Answer:
Step-by-step explanation: The rate of change at which the water level rises is centimeters per minute. So, solving the
equation for y gives a y-value equal to 1.
