Time taken for work out was 1/4 hours
let the time taken to walk be x
time spent for jogging will be (1/4-x)
distance=speed×time
distance walked will be:
3.1x miles
distance jogged will be:
5.2(1/4-x) miles
Total distance:
3.1x+5.2(1/4-x)=1.09
solving for x we get
3.1x-5.2x+1.3=1.09
2.1x=0.21
x=0.1
Thus time spent on waling was o.1 hours
time spent on jogging was 0.25-0.1=0.15 hours
0.017779534 because you just divide it
Answer:
26hr
Step-by-step explanation:
12 calls/hr
480 calls/wk
If Juanita has made 168 calls this week, it meants she still has to make 312 calls. So, 312 calls ÷ 12calls/hr = 26hr
Juanita needs to work 26hr mores to reach the weekly goal.
<u>Answer:</u>
<h2>12 ft</h2>
<u>Explanation:</u>
we will use pythagoras theorem
a² + b² = c²
according to the given data we'll assume that
a = 5
c = 13
5²+b²=13²
25+b²=169
b²=169-25
b²=144
b=√144
b=12
Step-by-step explanation:
$20/hr carpenter pay
$25/hr blacksmith pay
Let c = hours working carpentry
Let b = hours working as blacksmith
c + b = 30 {equation 1}
20c + 25b = 690 {equation 2}
In equation 1 solve for one variable in terms of the other.
c = 30-b
Substitute that into equation 2:
20(30-b) + 25b = 690
600 - 20b + 25b = 690
5b = 90
b = 90/5
b = 18 hours working as a blacksmith
c = 30-b = 30-18 = 12 hours as a carpenter
