Acar travels at a constant speed. what is the cars speed between checkpoints expressed as a unit rate? checkpoint as time being 1: 00pm total miles driven being 120 and checkpoint bs time being 3: 00pm and the total miles being 208

Checkpoint A-> time being 1:00pm total miles driven being 120 and

checkpoint B-> time being 3:00pm and the total miles being 208

The distance between two checkpoint A  and B is 208 - 120 = 88 miles

Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours

We need to find car speed between the checkpoints

We know Distance = speed * time

Speed = 44 miles per hour

answer: i'm great at algebra

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
