The answer to this equation will be 359
Answer:
=561.2 square feet
Step-by-step explanation:
top rectangle=19×8=152
bottom rectangle=5×8=40
two slanting rectangles=8×14×2=224
two side trapezium=(19+5)÷2=12
1/2×12×12.1×2=145.2
add them all
152+40+224+145.2=561.2
His average speed for the first trip is 43 mph
Since Brian's average speed is x and he travels the first part for 215 miles in time t.
So, his distance d = xt
Also, the travels 75 more miles at a speed of 15 mph.
Since distance = speed time, the time he takes to cover this distance is
t' = distance/speed = 75 mi/15 mph = 5 hours
Since he covers both distances in the same time, we have that t = t' = 5 hours.
So, his average speed for the first trip x = d/t
= 215 mi/5 h
= 43 mph
His average speed for the first trip is 43 mph
