A truck covers a particular distance in 3 hours with the speed of 60 miles per hour. If the speed is increased by 30 miles per hour, find the time taken by the truck to cover the same distance. using y=kx​

9514 1404 393

  2 hours

Step-by-step explanation:

Time, speed, and distance are related by ...

  d = st

The distance covered is ...

  d = (60 mi/h)(3 h) = 180 mi

Then the time taken at the higher speed is ...

  180 mi = (60 mi/h +30 mi/h)(t)

  t = (180 mi)/(90 mi/h) = 2 h

The time taken at the higher speed is 2 hours.

it 2

step-by-step explanation:

8^1/3=2

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
