It takes 0.26 minutes to travel 1000 feet
<u>Solution:</u>
Given that car traveling at a constant speed travels 175 miles in four hours
Distance = 175 miles
Time taken = 4 hours
Convert the units to feet and minute
Given that,
1 mile = 5280 feet
175 miles = 5280 x 175 feet = 918720 feet
Also we know that,
1 hour = 60 minutes
4 hours = 60 x 4 minutes = 240 minutes
Thus, we got,
Distance = 918720 feet
Time taken = 240 minutes
<em><u>Find the speed of car</u></em>
<em><u>Speed is given by formula:</u></em>


Thus speed of car is 3828 feet per minute
<em><u>How many minutes will it take for the car to travel 1000 feet?</u></em>
Let "x" be the minutes needed for 1000 feet
speed of car is 3828 feet per minute
1 minute = 3828 feet
x minute = 1000 feet
This forms a proportion. We can solve by cross multiplying

Thus it takes 0.26 minutes to travel 1000 feet
Answer:
solute and solvent
Explanation:
Because solutes dissolves in solvent to form a solution
Answer:
mass of substance =50.4 g
Explanation:
Using the density formula;
Density = mass of substance / volume of substance
Therefore, making mass subject of the density formula,
mass of substance = volume of substance / density of substance
volume of substance = 60.5 mL, density = 1.20 g/mL ( since common units of density is either g/cm³ or g/mL)
mass of the substance = 60.5 mL / 1.20 g/mL
mass of substance = 50.4 g
