Answer:
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
Step-by-step explanation:
Jamal's speed is of x mph.
Diego's speed is of (x + 7) mph.
Opposite directions.
This means that each hour, they will be x + x + 7 = 2x + 7 miles apart.
After 4 hours they are 68 miles apart, how fast is each traveling?
Using a rule of three.
1 hour - 2x + 7 miles apart.
4 hours - 68 miles apart.
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
Is there like a question on paper with choices? It’s kind of confusing when you need to multiply yourself, and it seems like there would be a A, B, C, D on this.
Answer:
D
Step-by-step explanation:
For this type of problem, we need to think of it as a ratio.
The first tree to shadow ratio would be 40:12 this can be simplified to 20:6 which can be simplified to 10:3.
The second ratio is 5:x. I say x because it's an unknown number. Since 5 is half of ten, then the x would be half of three. Therefore the answer is D.
The answer is:
