Mr. sam took 1 h 15 min to drive from his home to office. if the distance between his home and office was 50 miles, at what average speed did mr. sam drive? mph

The average speed of Mr Sam is 40 mph.

The given parameters;

time of the motion from home to office = 1 hr 15 min = 1.25 hr

the distance between the home and office = 50 miles

The average speed of Mr Sam is the ratio of the total distance traveled by Mr Sam to the total time of the motion.

The value of the average speed is calculated as follows;

Thus, the average speed of Mr Sam is 40 mph.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
