A car travels 30 1/5 miles in 3/4 of an hour. What is the average speed in miles per hour of the car

Divide miles driving by time.

Rewrite miles as improper fraction:

30 1/5 = 151/5

151/5 / 3/4

When dividing fractions change to multiplication and flip the second fraction over:

151/5 x 4/3 = 604/15 = 40 4/15 miles per hour

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
