A. 78 km/h

B.  9.75 km/l

C. 64.28571 km /h

Step-by-step explanation:

2.5 hours, drove 195 km, used 20 liters for whole journey

A. avg speed

speed = distance / time

speed = 195 km / 2.5 hours

speed = 78 km per hour

B. gasoline consumption rate in km/l

rate = kilometers / liters

rate = 195 km / 20 l

rate = 9.75 km/l

C. avg speed of 110 km/h for 45 mins, what is avg speed for remaining part?

distance = speed * time

distance = 110 km/h * 0.75 h

distance = 82.5 km

total distance = 195, 195-82.5, he has 112.5 km left to go for the trip

105 minutes left (2.5*60 - 45 = 105)

speed = distance / time

speed = 112.5 km / 1.75 h

speed = 64.28571 km /h

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
