Sarah drove 40 miles per hour. in 3 hours, sarah drove 120 miles. what is a valid proportion to represent the problem?

As per the statement:

Sarah drove 40 miles per hour in 3 hours,  Sarah drove 120 miles.

Since, speed(s) is proportional to time(t)

Using Inverse proportional.

⇒, where, d is the constant distance

We can write this as:

or

Check:

Sarah drove 40 miles per hour in 3 hours

⇒s = 40 miles per hour and t = 3 hours

then;

⇒Sarah drove 120 miles.

therefore, a valid proportion to represent the problem is,

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
