Someone please help me with this Your distance from lightning varies directly with the time it takes you to hear thunder. If you hear thunder 10
seconds after you see the lightning, you are about 2 miles from the lightning.

a. Write a direct variation equation for the relationship between time and distance.

b. Estimate how many seconds it would take for the thunder to travel a distance of 4 miles.

b. 20 seconds

Step-by-step explanation:

Let be the distance in miles and

be the time in seconds and

be the speed in miles/sec

Formula for Distance is given as:

Given that:

Distance = 2 miles and

Time = 10 seconds

Putting the values in formula:

Answer a:

Putting the value of back in the formula to find the direct variation equation for the relationship between time and distance:

Answer b:

Using the above formula and putting :

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
