1. Given that Lindsay went for a drive. she used gallon of gas every of an hour. Now we need to solve for her gallons per hour.

To find value for 1 unit for any similar problem we just divide one quantity by another quantity

so we will use same logic here of an hour uses gallon of gas

then 1 hour uses \frac{\left(\frac{8}{3}\right)}{\left(\frac{4}{5}\right)} gallon of gas

= = = Hence final answer is gallons per hour.

2. A = amount of gas used for the drive = 8/3 gallon

t = duration of time in which amount of gas A is used =  4/5 hours

r = rate of gas used

rate of use of gas is given as the ratio of gas used in the amount of time given.

hence , rate of gas used is given as

R = A/t

inserting the values given above

R = (8/3)/(4/5)

R = 8 x 5/(3 x 4)

R = 40/12

R = 3.33 gallons per hour
