Unit rates and rate problems flashcards

Question 1

What is a rate?

Accepted Answer

A rate is a ratio that compares two quantities measured in different units (like miles per hour).

Question 2

When do you use unit rates?

Accepted Answer

Use unit rates to compare deals, compare speeds, or convert to a “per 1” amount (like cost per item).

Question 3

A car travels at a constant rate of 65 miles per hour. Write an equation for distance $d$ after $t$ hours and find $d$ when $t=3.5$.

Accepted Answer

$d=65t$ (miles, with $t$ in hours). For $t=3.5$, $d=65\cdot 3.5=227.5$ miles.
