Ted drove to his grandparents' house for a holiday weekend. the total distance (one-way) was 482 miles and it took him 6 hours. how fast was ted driving? (round answer to the nearest whole number)

Ted was driving at a speed of 80 miles/hour.

Explanation

Suppose, the speed of Ted is   miles/hour.

Relationship between Distance, Speed and Time is....

Given that, the total distance was 482 miles and it took him 6 hours.

So, according to the above formula....

So, the speed of Ted after rounding to the nearest whole number will be 80 miles/hour.

By definition we have that the speed is given by:

Where,

d: distance traveled

t: time

Substituting values we have:

Rounding to the nearest whole number:

Ted's speed is 81 mph.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
