Answer:
5 mph
Step-by-sep explanation:
To find of out the difference between the speed of the two drivers in miles per hour (not in miles per minute), first, calculate the unit rate or speed of driver 1 using the graph, and driver 2 using the table given.
Unit rate/speed = distance travelled/time = y/x.
Speed of Driver 1/unit rate:
The graph shows 1.5 miles (y) is travelled in 2 minutes (x).
Convert the 2 minutes to hour, you will have:
Speed in mph =
Speed of Driver 1 in mph = 45 mph
Speed of Driver 2/unit rate:
The table shows 2.5 miles (y) is travelled in 3 minutes (x).
Convert the 3 minutes to hour, you will have:
Speed in mph =
Speed of Driver 2 in mph = 50 mph
Difference between the speed of the two drivers = 50 - 45 = 5 mph
Claire's time to mow all the lawns last week was 1.4 times longer than this week.
<em><u>Explanation</u></em>
Claire mowed each lawn in hour last week.
So, the <u>total time taken to mow all 4 lawns last week</u> hours.
She mowed the same lawns this week and took hour for each.
So, the <u>total time taken to mow all 4 lawns this week</u> hours.
Now.....
<u><em>(Total time in last week / Total time in this week)</em></u><em> </em>
So, Claire's time to mow all the lawns last week was 1.4 times longer than this week.
