Answer:
<h2> 245miles</h2>
Step-by-step explanation:
Step one:
given that the first 3 hours the train travels at a speed of 45 mph.
i.e Time = 3 hours
speed =45 mph
distance=?
we know that speed = distance/time
distance= speed*time
distance= 45*3
distance=135miles
Step two:
For the nex two hours it travels at 55 mph
i.e time= 2hours
speed= 55mph
distance=?
distance= speed*time
distance= 2*55
distance= 110mile
Step three:
Hence for a total of 5 hours drive, the total distance covered is
135+110= 245miles
47 is the answer Since two opposites add up to zero, remove them from the expression, and then you just add up the answers
Answer:
51ft, 17ft, 39ft
Step-by-step explanation:
longest = x
2nd = 
x
3rd = x - 12
P = 107
a + b + c = Perimeter
x + x + x - 12 = 107
x -12 = 107
x = 119
x = 51
x = 17
x - 12 = 39
