Answer:
8, 18 and 36 respectively.
<h2>explanation</h2>
sum=54
1st number=x
2nd number=x+10
3rd number =2(x+10)=2x+20
x+x+10+2x+20=54
put the liketerms together
x+x+2x=54-10-20
4x=24
divide both sides by 4 to get
x=8
Input the other values
Answer:
180 miles
Step-by-step explanation:
This is a distance-rate-time problem. We need to use the equation: d = rt, where d is the distance, r is the rate, and t is the time.
Here, r = 60 mph and t = 3 hours. Plug these in to find d:
d = rt
d = 60 * 3 = 180 miles
Hope this helps!
So to begin your problem, you know that your car already has an average which is 65km/45 mins. The problem wants you to change this to km/hr. This means that you need to convert minutes to hours. A simple way to do this is by using fractions.
Set your problem up with fractions similar to this:
65km/45 mins x 60 mins/1 hr.
the whole point is to cancel out your minutes, and leave the hours as your new unit for the denominator
65km/45 x 60/1 hr.
now you want to reduce (I divided the first fraction by 5)
13km/9 x 60/1 hr.
780km/9hrs.
That would be your answer. If someone can double check my math that would be fantastic.
