The average speed would be 600 km/hr.
Step-by-step explanation:
Let the original speed be 'x'
Let the decreased speed be 'x-200'
Distance = 600 km
Time increased by 30 minutes
According to question, it becomes,
So, The average speed would be 600 km/hr.
Answer:
2.46 miles
Step-by-step explanation:
For this problem, you would have to start off with an equation. So, the equation would be: 19.95+91x=243.81 once we subtract 19.95 on both sides and divide the result by 91, the answer will be 2.46 miles
Answer:
range = bigger number-smaller number
biggest number=166
smallest number=111
166-111
=55
Answer:
0.0357
Step-by-step explanation:
We have the following important data:
- One in 10 middle-aged men is very active, and the rest are classified as sedentary.
- Men who were very active (burning about 3,500 calories daily) were a third as likely to develop diabetes.
- From point 1) we can say that the relation between very active and sedentary men is 1 to 9. That is, for each very active man there are 9 sedentary men.
- From point two we can say that, if we had the same number of sedentary and very active men, then there would be 3 times more sedentary men with diabetes than very active men with diabetes.
But we do not have the same number of sedentary and very active men. There are 9 times more sedentary than very active. Therefore, there would be 9*3=27 times more sedentary men with diabetes than very active men with diabetes.
In conclusion, the probability that a middle-aged man with diabetes is very active is
If you give me some true or false questions I would be glad to answer them for you, but sadly I don't know what book or page you are on, so I cannot help.
