A man walked steadily from 11 am to 2.30 pm at 5 kilometres per hour how far did he walk!
1 answer:
Answer:
Distance traveled 17.5 kilometers
Step-by-step explanation:
We can use the following equation to find the distance traveled,
Distance traveled = Speed * Time
First we need to find the total time he walked = 2.30 p.m. - 11.a.m.
= hours
Now we can substitute the values to the equation,
Distance traveled = kilometers per hour *
hours
= kilometers
= 17.5 kilometers

Answer:
The solution of the system is the ordered pair (-13,-4)
Step-by-step explanation:
we have
-----> equation A
----> equation B
Solve the system by elimination
Multiply by 2 both sides equation B
----> equation C
Adds equation A and equation C
<em>Find the value of a</em>
substitute the value of b in any equation (i take equation B)
therefore
The solution of the system is the ordered pair (-13,-4)
