It takes 3 hours 15 minutes to fly from ato b at constant speed. Find howlong the journdy takes if(a) the speed is3÷2 times that of the original speed (b) if the speed is three_quarters of the original speed.

For 3/2 of the speed = 292.5 minutes

For 3/4 of the speed =  146.25 minutes

Step-by-step explanation:

It takes 3hrs 15 minutes to fly from A to B

From A to B = 180minutes + 15 minutes

= 195 minutes (At constant speed)

At constant speed,

If the speed is 3/2 of the original speed,

It will be,

3/2 X  (195 minutes) = 585 / 2 = 292.5 minutes

On the other-hand,

If the speed is 3/4 of the original speed,

3/4 X (195 minutes) = 585 / 4 = 146.25 minutes

step-by-step explanation:

sry but any answer choices

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.
