Sara's mother takes her to her grandparents' house for dinner. She drives 60 minutes at a constant speed of 35 miles per hour. She reaches the highw 30 minutes at a constant speed of 60 miles per hour. How long did it take Sara's mother and how far did she drive? А It took her 65 minutes and she drove 90 miles.

B It took her 90 minutes and she drove 65 miles. 000

C It took her 90 minutes and she drove 95 miles.

D It took her 65 minutes and she drove 60 miles.

add the two parts of the trip together.. the slow part + fast part = total

Step-by-step explanation:

slow part = 35 miles

fast part = 30 mins at 60  mph  = 30 miles ( 1/2 of 60  b/c 30 mins is 1/2 an hour)

so

35 + 30 =65 miles, in  1.5 hours =  1 hour and 30 mins =  90 mins

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )
