Answer:
The speed of the faster cyclist is 15 miles per hour
Step-by-step explanation:
Let the speed of the slower cyclist be x miles per hour
The speed of the faster is 3 times this
Mathematically, we have this as 3 * x miles per hour = 3x miles per hour
Now;
distance = speed * time
In 4 hours, the distance covered by the slower will be;
x * 4 = 4x miles
The faster;
3x * 4 = 12x miles
Since they are riding opposite each other, they would have covered a total distance of 80 miles when they meet
Thus, we have that;
12x + 4x = 80
16x = 80
x = 80/16
x = 5
The speed of the faster is;
3x miles per hour
Substitute the value of x here
That will be;
3 * 5 = 15 miles per hour
Answer:
D 4 places to the left
Step-by-step explanation:
Okay, think of it as a pie. They ate 3/4 of the pie, leaving 1/4. Then that 1/4 was cut into 6/6, and 1/6 was eaten. So there were 5/6 left of that 1/4. Your pie has 4 quarters, and each is made up of 6 mini pieces, so 6 x 4 = 24. There were 24 little 1/6 pieces at the beginning when your lasagna pie was whole. Now, at the end, you have 5 of them left. So you have five of the original 24—
