Answer:

11/40 + 1/4 + 1/20

Step-by-step explanation:

Draw a Venn diagram: (as shown)

Consumer Ed. : 22-4=18

French : 20-4=16

Neither : 80-18-16-4=42

Using probability notation where P(A) means probability of event A occurring.

P(Consumer Ed.) = 22/80

P(French) = 20/80

P(Both) = 4/80

<em>'or ' </em>in the question means you add.

=> 22/80 + 20/80 + 4/80

=> 11/40 + 1/4 + 1/20

jayln rode her bike in a bike a thon she rode 33.48 miles in 2.7 hours if she rodeat the same speed what is her speed in mph

kari74 [83]

Answer:

Jayln rode 12.4 miles/hour.

Step-by-step explanation:

The question is asking for a unit rate for the speed in miles per hour that Jayln rode her bike over her 33.48 mile ride. Since we know that she rode a total of 33.48 miles and the total time was 2.7 hours, we can set up our ratio as 33.48/2.7 or miles/hours. In order to find unit rate, or the number of miles per one hour, we need to divide: 33.48 ÷ 2.7 = 12.4. So, 12.4 mph is Jaylyn's speed.
