When the lightning occurs 4.5 km away then we will hear after 13.5 seconds and if we hear after 1.5 seconds then we are 0.5 km away from lightning.
Given With each km from the lightning 3 seconds passes.
a) The table of values for distances from 0 to 5 km.
Distances Time
0 0
1 3
2 6
3 9
4 12
5 15
b) The graph of lightning is a linear relation because it is increasing constantly by 3 seconds. f(x)=3x
c) When distance =1 , the time be 3 seconds
when distance =4.5 , the time=3*4.5
=13.5 seconds.
d) When time is 3 seconds = 1km
when time =1.5 seconds , the distance be 1/2=0.5 km.

Answer:
4t miles per hour
Step-by-step explanation:
Distance refers to the amount of space an object can cover within a period of time. It can be calculated by multiplying speed and time.
Distance= speed × time
Speed is the rate of movement of an object from one place to another.
Speed= Distance/Time.
Time= distance/speed.
If Katie walks at the rate of 4miles per hour.
Her total distance in the hours is d
Total distance= speed× time
Her speed=4miles per hour
Time= t
Katie's total distance=4 miles per hour× t
=4t miles per hour
Answer: D.
Step-by-step explanation: Add all of the sides' lengths together. The rest of the wall beneath where "5 ft." is measures as 6 ft. Add that to the 5 ft of the rest of the wall and you'll have 11 for the whole right wall. Add 11 to 8, 10 and 12, and you'll have 41 which is close to the last choice so you're safest bet is D.
