The time it takes you to get to campus varies inversely as your driving rate. averaging 20 miles per hour in terrible traffic,

Korvikt [17]

Given that the time taken to get to campus is inversely proportional to driving rate, let the time be t and rate be r, thus the function will be written as:'
t=k/r
where
k is the constant of proportionality given by:
k=tr
when r=20 mph, t=1.25 hrs
thus
k=20×1.25
k=25 miles
thus the formula is:
t=25/r
when r=55 mph, the value of t will be:
t=25/55
t=5/11 hours

The distance between Alphaville and Betaville is seven hundred and

LenKa [72]

Answer:

Step-by-step explanation:

Distance = speed × time

A car from Alphaville to Betaville is moving at a speed of sixty-two miles per hour. This means that after two and a half hours, the distance that this car would have covered is

62 × 2.5 = 155 miles

Another car from Betaville to Alphaville is moving at a speed of fifty-seven miles per hour. This means that after two and a half hours, the distance that this car would have covered is

57 × 2.5 = 142.5 miles

A and B represents Alphaville and Betaville as well as the first and second cars. The total distance covered by both cars is

155 + 142.5 = 297.5 miles

The distance between both cars after two and a half hours is

725 - 297.5 = 427.5 miles
