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.
Martinus Kupier skate a distance of 340.8 miles, at an avarage of 14.2 mph for 24 hours
Step-by-step explanation:
The given is,
Martinus Kupier skated for 24 hours at an average rate of 14.2 mph
Step:1
From the given the time and average rate is obtained,
Time = 24 hours
average rate = 14.2 mph
Step:2
To find the total length of skated at 24 hours
Length = Average rate × Time
= 14.2 × 24
= 340.8
Length = 340.8 miles
Result:
Martinus Kupier skated a distance of 340.8 miles at an average rate of 14.2 mph for 24 hours.
Answer:
X=11
Step-by-step explanation:
The answer is 35. To find it, put the numbers in chronological order, the split the set in half. Find the middle of the first half, which is 49. Then, find the middle of the second half, which is 84. Lastly, subtract 49 from 84 to get 35! Hope that helps!
Answer:
<u>1. 4/13 = 20/65
</u>
<u>2. 4/20 = 13/65 </u>
<u>3. 5/10 = 23/46</u>
<u>4. 5/10 = 32/64
</u>
<u>5. 5/23 = 10/46
</u>
<u>6. 5/32 = 10/64</u>
Step-by-step explanation:
We can make the following six equivalent ratios using the digits from 0 to 6 only once:
1. 4/13 = 20/65 (We multiply 4 and 13 by 5 to get the second equivalent ratio)
2. 4/20 = 13/65 (We divide the first ratio by 4 and the second by 13 and we get 1/5 on both ratios)
3. 5/10 = 23/46 (We divide the first ratio by 5 and the second by 23 and we get 1/2 on both ratios)
4. 5/10 = 32/64
(We divide the first ratio by 5 and the second by 32 and we get 1/2 on both ratios)
5. 5/23 = 10/46
(We multiply 5 and 23 by 2 to get the second equivalent ratio)
6. 5/32 = 10/64 (We multiply 5 and 32 by 2 to get the second equivalent ratio)
