The equation in terms of x, for the total time he takes in hours would be 2.48 = 12/x + 26/10x
<h3>What is speed?</h3>
Speed can be calculated as the ratio of distance traveled to the time taken
Darpan runs a distance of 12 km and then cycles a distance of 26 km.
Total distance = 12 + 26 = 38km
The running speed is x km/h
A = x
The cycling speed is 10 km/h faster than his running speed
B = 10x
He takes a total time of 2 hours and 48 minutes.
So, the total time he takes
Time = Distance x speed
2.48 = 12/x + 26/10x
10x(2.48) = 120 + 26
24.8x = 146
x = 5.8

Answer:
1 1/6
Step-by-step explanation:
4 2/3 ÷ 4
Convert the mixed number into an improper fraction:
4 2/3 = 14/3
14/3 ÷ 4
14/3 ÷ 4/1
Use cdf (copy dot flip)
14/3 × 1/4
14 × 1 / 3 × 4
14/12
Convert improper fraction into a mixed number:
14/12 = 1 2/12
1 1/6

Answer:
81 1-inch cubes
Step-by-step explanation:
Cube root of 729 is 9
9 x 9 = 81
Further explanation:
A cube has 3 measures (there are all the same) to solve for the volume. If the volume is 729, and it is a cube, you would solve for the cube root, because all the numbers are the same. Then, we would get 9. Now, since a cube is made up of faces, and each one is a square, we do 9 x 9 to get the area, which is the answer, because 1-inch cubes are literally just units.
