Craig Drives 20 miles per hour faster than sara in the same

Craig Drives 20 miles per hour faster than sara. in the same time that sara drives 225 miles, craig drives 325 miles. find the speed of each car

d=vt so t=d/v
Let x=sara\'s speed
Then x+20=craig\'s speed
225/x=325/(x+20)
Multiply both sides by x(x+20)
225(x+20)=325x
225x+4500=325x
100x=4500
x=(Sara\'s speed) 100 mi/hr
x+20=(Craig\'s speed) 120 mi/hr
