Answer:
Ascending order is given by
1/50<1/23<1/17<1/12<1/9<1/7<1/5
Descending order is given by
1/5>1/7>1/9>1/12>1/17>1/23>1/50
Step-by-step explanation:
We are given that
1/12,1/23,1/5,1/7,1/50,1/9,1/17
We have to arrange the numbers in ascending and descending order.
LCM of 12,23,5,7,50,9,17
=73899000
14779800>10557000>8211000>6158250>4347000>3213000>1477980
Therefore,
Ascending order is given by
1/50<1/23<1/17<1/12<1/9<1/7<1/5
Descending order is given by
1/5>1/7>1/9>1/12>1/17>1/23>1/50
Answer:
60 m/h
Step-by-step explanation:
1. the basic formula is Time=Distance/Speed;
2. total time is time1 (for 84 miles)+time2 (for 130 miles)=time (4 hours);
3. the time for the first 84 mi. is time1=84/S;
4. the time for the rest 130 mi. is time2=130/(S-10);
5. using all the data of items 2-4, it is possible to substitute into the basic formula and resolve an equation:
note, that the value of speed has one condition: s>10. It means, the only value is true: 60 miles per hour.
