if he reduced his speed by 0.1 miles per hour, he would then be traveling at a rate of 25.78 miles per hour. this is almost identical to the question above … but you now are breaking (or dividing) the total into “groups” of 25.78. each of these “groups” again is an hour. to find out by how much his time changed, you need to find the “difference” which is the answer to a subtraction problem. subtract the two numbers and that is the difference or amount of change.

25.88 miles/ 1hr therefore he’s going 25.88 mph

then you’ve got his miles but no time so you do

2242 miles/ X hours

Have you done this yet? If I remember correctly you have to multiply in X “design”

1 x 2242 miles giving you 2242

Then you take your 2242 and divide it by the remaining numeral which is 25.88 therefore giving you your X which will be 86.63 hours

If you’ll write it down on paper and put 25.88 miles over 1 hour and then put 2242 miles over X you should see what I mean. When you see what I mean do the equation the same way for question b. but just change your 25.88 to 25.78. I HOPE i helped!

a)

2242 miles = 25.88 miles/hour x Time

2242/25.88 hours = Time

b)

2242 miles = (25.88-0.1)miles/hour x Time

2242 miles = (25.78) miles/hour x Time

2242/25.78 hours = Time

The Change in Time is

[ (2242/25.78) – (2242/25.88) ] hours

Use long division to covert the fractions into a decimal number

2,242 miles divided by 25.78 MPH = 86.96664 hours

86.96664 hours – 86.6306 hours = .336041 hours

d=distance (2,242)

r=rate of travel (25.88mph)

t=time (unknown)

2,242=25.88x

/25.88 /25.88

86.6 = x

87hours = x

2,242=25.78x

/25.78 /25.78

86.96 = x

87hours = x
