Question

In a race, Car #1 went an average of 165 miles per hour for x hours before dropping out. Car #2 went an average of 175 miles per hour for y hours before dropping out. The distance Car #1 travelled was at least that of Car #2. Using the values and variables given, write an inequality describing this.

Answer 1

When you think about it. It's actually quite easy.
The number are the amount of miles, and the variables are the amount of hours. So we would just have to multiply them. So, by putting the number together we would be able to multiply them once we have the numbers for the variables. Since we dont have them, we can just make the inequality. It says that car 1 traveled at LEAST that of car 2. Showing that car 1 may have traveled farther. SOOOOO........ the inequality should look like this:

165x ≥ 175y

Answer 2

165x ≥ 175y

Explanation:

Car # 1 went with an average speed of 165 miles per hour.

Time of run = x hours

Since Distance = Speed × time

Distance = 165x miles

Car # 2 traveled with an average speed = 175 miles per hour

Duration by which car traveled = y hours

Distance traveled = Speed × time

= 175y miles

The distance car #1 traveled was at least that of car #2.

That means Distance traveled by car #1 ≥ Distance traveled by car #2

165x ≥ 175y
