Answer:
6.5 miles in 1 hour and they will run 75% of the full distance in 1 hour.
Step-by-step explanation:
The distance covered by two marathon runners = 26 miles
They takes 4 hours
We need to find how many miles did they run in 1 hour
In 4 hour, the distance covered is 26 miles
To find distance covered in 1 hour, divide 26 by 4 such that.
So, they will cover 6.5 miles in 1 hour.
For percentage,
So, they will run 75% of the full distance in 1 hour.
Answer:
I have no idea
Step-by-step explanation:
We have two widths of the same length plus one length
Let the width be
and the length be
Perimeter = 2×width + 2×length
(equation 1)
The cost is $5 per foot on the width and $25 per foot on the length
Total cost = (5 × 2 × width) + (25 × length)
(equation 2)
We have two variables that we need to solve, so we will need to use the simultaneous equations method (either elimination or substitution)
Since equation 1 is given
, we can rearrange the equation to make
the subject
then substitute this into equation 2
Substitute w = 75 back into 190 = w + l
190 = 75 + l
l = 190 - 75
l = 115
Answer:
Length = 115 feet
Width = 75 feet
4 sweets = 28p
1 sweet = 7p
7 sweets = 7 x 7 = 49p
