An object is traveling at a steady speed of 10 1/10 km/h. How long will it take the object to travel 1 9/10 km?

It will take hour.

Step-by-step explanation:

The rule of the distance is:

Distance = speed × time

∵ An object is traveling at a steady speed of km/h

∴ The speed =   km/h

∵ The object will travel km

∴ The distance =   km

→ We need to find how long will it take it to travel this distance

→ Substitute the values of distance and speed in the rule above

∵    =   × time

→ To find the time divide both sides by  

∴ The time =     ÷  

→ Change the mixed numbers to an improper fraction

∵   =

∵  

∴  The time = ÷

- Reverse the fraction after the division sign, then change ÷ to ×

∴ The time =   ×

→ 10 up will cancel 10 down

∴ The time =   h

It will take hour.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
