a.
Answer to Problem 22PPS
The linear equation to find the distance of the remote control car from Greg is
Explanation of Solution
Given: A person is driving the remote control car at constant speed. And he starts the timer when the car is 5 feet away. But, after 2 seconds the car is 35 feet away.
Calculation:
Considering at time
Hence, the distance travelled by the car from time
So, speed of the car is evaluated as,
Also, initially the car is 5 feet away. Therefore, the distance
b.
The distance travelled by the car after 10 seconds.
b.
Answer to Problem 22PPS
The distance travelled by the car after 10 seconds is 155 feet.
Explanation of Solution
Given: A person is driving the remote control car at constant speed. And he starts the timer when the car is 5 feet away. But, after 2 seconds the car is 35 feet away.
Calculation: From (1), the distance travelled by the car after
As per the problem, the distance travelled by the remote control car after 10 seconds can be evaluated by plugging
