The faster Luis drives, the less time it will take him to get to Houston. This is an inverse relationship. Let y = time driving and x = speed. If it takes him 3 hours to travel there and he goes at 70 miles per hour, how long will it take him to get there at 80 miles per hour? Round your answer to the nearest tenth of an hour.

Respuesta :

The time it would take if he drives at 80 miles per hour is 2.6 hours.

How long would the journey take if he drives at 80 miles per hour?

if two variables vary inversely, there is a negative relationship between both variables.

The equation that represents inverse proportion : y = k/x

where b = constant of proportionality

3 = k / 70

k = 3 x 70

k = 210 miles

t = 210 / 80

t = 2.6 hours
