Answer:
2=x
Step-by-step explanation:
-2x+5=4x-7
+2x +2x
5=6x-7
+7 +7
12=6x
/6
2=x
Total miles traveled in p hours = p*q miles and
Total miles traveled in r hours = r*s miles
so, average rate of speed = total miles traveled / number of hours
=[{(p*q)+(r*s)} / (p+r)] miles per hour
Answer:
8
Step-by-step explanation:
4x +5 = 37
4x + 5 - 5 = 37 - 5
4x = 32
4x/4 = 32/4
x = 8
hope this helps
Answer:
Speed = 0.0003miles/hr
Step-by-step explanation:
Speed of object = 1 mile/hour
For every meter it travels, its acceleration increases by 1 mile/hour
∆Distance = increase in distance
∆speed = 1 meter
The speed and the distance are constant
Speed = distance/time
Time = distance/speed = 1meter/(1 miles/hr)
Convert meter to miles
1609.34 meters = 1mile
1meter = (1meter × 1mile)/(1609.34 meters)
1 meter = (1/1609.34)miles
Time = distance/speed = (1/1609.34)miles/(1 miles/hr)
Time = (1/1609.34)hr
We are to determine the speed the object would be travelling in half of an hour?
In 1hr, it travels (1/1609.34)miles
In ½hr, it travels = (1/1609.34)(½)hr
Speed = 0.0003miles/hr
It will be travelling 0.0003miles/hr in half of an hour
