Pauline travels between two cities. first she drives for 40 minutes at an average speed of 88 km/hr then for 40 minutes at an average speed of 75 km/hr, then she spends 17 minutes eating lunch and buying gas, and then she drives for 23 minutes at an average speed of 49 km/hr. find pauline's average speed for this trip. express it in kilometers per hour and round your answer to the nearest km/hr.

Pauline's average speed for this trip is 64 km/hr.

Explanation

First we will convert each 'minutes' into 'hours' . So......

40 minutes = and 23 minutes =

Now,  

So, the distance traveled for first 40 minutes at 88 km/hr speed ,

the distance traveled for next 40 minutes at 75 km/hr speed and

the distance traveled last 23 minutes at 49 km/hr speed

So, the total distance traveled

She spends 17 minutes eating lunch and buying gas.

So, the total time taken for the trip

Thus, Pauline's average speed for this trip = (Total distance / Total time) (Rounded to the nearest km/hr)

hey there!

12 is twice as much as 6 because 6 goes into 12 2 times.

since the rabbit is twice as tall, we should multiply the weight of the first rabbit, 0.25, by 2.

0.25 x 2 = 0.5

therefore, the 12 inch chocolate rabbit weighs 0.5 lb, or half a pound.

hope this !

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2
