Estimate the time it would take you to drive 361 miles at 42 miles per hour. Round to the nearest hour.
polet [3.4K]

Answer:

It would take you 9 hours

Step-by-step explanation:

Speed (s) = Distance (d) / Time (t)

given that; Speed = 42 miles/hour

                 Distance = 361 miles

42 miles/hour = 361 miles / Time (t)

Time (t) * 42 miles/hour = 361 miles

Time (t) = 361 miles / 42 miles/hour

Time (t) = 8.59 hours

             ≈ 9 hours (to the nearest hour)

Pls answer I really need help<br> Brainlist and thank you will be the reward thank you so much!!!
castortr0y [4]

Answer:

<h2>0.667 ✅</h2>

Step-by-step explanation:

This is best solved using a proportion.

The formula is soy/vinegar = soy/vinegar where one of these is a variable.

Here we have:

\frac{150}{100} = \frac{1}{x}

Now, we solve this by cross multiplying.

150x = 100

Dividing both sides by x, we get x = 2/3 or about 0.667.

Checking:

\frac{150}{100} = \frac{1}{0.667}

1.5 = 1.5 ✅
