:) please respond quick and thorough!!!!

Answer 1

You went 48.75 miles. That's 1.95 gallons of gas. It cost $7.02

Answer 2

45 mins=3/4 of an hour aka .75. .75hrsX65mph=48.75miles

48.75miles/25mpg=1.95 gallons used to get to grandmas house

1.95gallonsX$3.60pg=$7.02, cost to travel to grandmas house

best answer?? plz lol

Answer 3

I'm not going to give you the answer but I'll write the equation for you.

1.  take 65 and multiply it by .75 because 45min is 3/4 of an hour.

2.  The answer is how many miles it is to grandma's house.so then you'd take the answer from #1 and divide by 25.. the mpg. and that is your answer.

Bonus. take your answer from #2 and multiply by 3.6 and that is how much it costs.

Good Luck
