Answer:
Distance = 10 km
Step-by-step explanation:
Let x be the number of hours taken from school to town and y be the number of hours taken back to the school
Then distance covered during first trip would be 10x (distance = speed*time) and during the second trip would be 8y. Both distances are equal.
=> 10x = 8y
Dividing both sides by 2
=> 5x = 4y
=> 5x-4y = 0 ------------------(1)
<u><em>The total time for both the trips is:</em></u>
=> x + y = 2.25 -------------------(2)
Multiplying eq (2) by 5
=> 5x+5y = 11.25 ---------------(3)
Subtacting (3) from (1)
=> 5x-4y-5x-5y = 0-11.25
=> -4y-5y = -11.25
=> -9y = -11.25
Dividing both sides by -9
=> y = 1.25 hrs
Putting in (2)
=> x + 1.25 = 2.25
=> x = 2.25 - 1.25
=> x = 1 hr
<u><em>Now, Calculating the Distance</em></u>
=> Distance = 10x
=> 10 ( 1 )
=> Distance = 10 km
Answer:
4 bags
Step-by-step explanation:
Step 1
1 bag = 24 oz
Hence:
1 ounce(oz) = 0.0625 pound
24 oz = x pound
Cross Multiply
x pound = 24 × 0.0625 pound
x pound = 1.5 pounds
Hence, 1 bag = 1.5 pounds
Step 2
If
1.5 pounds = 1 bag
5 pounds = x bags
Cross Multiply
1.5 x = 5 × 1
x = 5/1.5
x = 3.33 bags
At least 5 bags means exactly 5 bags or more
= 3 bags = 1.5 × 3 = 4.5 pounds
4 bags = 1.5 × 4 = 6 pounds
Therefore, he will need to buy 4 bags
at least 5 pounds
It all depends where you start from, and what route you take.
For me, if I take the shortest possible route, then it's 3,956 miles to London
and 9,809 miles to Jakarta. So for me, Jakarta is 5,853 miles farther.
But if you're starting from, say, Singapore, then London is 6,192 miles
farther away than Jakarta.
