Jasmine finished the bike trail in 2.5 hours at an average rate of 9 3/10 miles per hour. lucy biked the same trail at a rate of 6 1/5 miles per hour. how long did it take lucy to bike the trail?

plz explain your awnser

3.75 hours

Step-by-step explanation:

Using the relation

Distance = speed × time

Change Jasmine's speed into an improper fraction

9 = , then

distance = × = miles

To calculate Lucy's time over the same distance use

Time =

Change speed to an improper fraction

6 = , hence

time =

       = × ( cancel 93 and 31 )

      =

      = = 3.75 hours

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
