Answer:
minimum distance will be 13.33 m
Explanation:
We have given the speed of both the car = 80 km/h
We know that 1 km =1000 m
And 1 hour = 60×60 =3600 sec
So
Reaction time is given as t = 0.60 sec
Minimum distance will be equal to the distance driver needed during reaction time
So minimum distance = u ×t =22.22 ×0.60=13.33 m

Answer:
Her average speed was 40 km/h.
Explanation:
Hi there!
The average speed (a.s) is calculated as the traveled distance divided by the time it took to cover that distance:
a.s = d/t
Where:
d = traveled distance.
t = time.
In this case, the odometer reading of the car increased by 12.0 km, which means that the distance traveled is 12.0 km. The time it took the student to cover that distance is 18.0 min (18.0 min · 1 h/60 min = 0.3 h) . Then the average speed will be:
a.s = d/t
a.s = 12.0 km/ 0.3 h
a.s = 40 km/h
Her average speed was 40 km/h.
Answer:
