Question

If Sara drives 60 miles per hour, it takes her 2 hours to reach her parents' house. Write an equation describing the relationship between Sara's speed and the time it takes her to get to her parents' house. (Note that speed and time are inversely proportional).
Question 17 options:

A)

s = 120∕t

B)

s = 60∕t

C)

s = 24∕t

D)

s = 30∕t

Answer 1

Answer: (A) .                                                                                                          

because if you travel 60 miles per hour and i takes 2 hours yto get there you have to double 60 miles so 120 miles per 2 hours

Answer 2

The relationship between Sara's speed and the time it takes her to get to her parent's house will be s = 120/t so option (A) will be correct.

What are work and time?

Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.

Another illustration of labor is when you finish your meal in an hour, which means that you finished your work in an hour. In essence, work is the length of time it took you to complete any task.

Given that Sara drives 60 miles in 2 hours.

Distance covered by sara is = 60(2) = 120 miles.

We know that

speed = distance/time

Let's say speed is S time is t then

⇒ S = 120/t so the correct equation of the given question will be this.
