Arace car driver must average at
least 100 mi/hour for two laps around
a track to qualify for the finals. because
of mechanical trouble, the driver is only
able to average 50 mi/ hour for the first
lap. what minimum speed must the driver
average for the second lap to qualify for
the finals?

50

Step-by-step explanation:

So if the driver is going 50 on 1 lap. He must average out another 50 to make the 100

idk

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
