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
Answer:
j(x) = 150x
Step-by-step explanation:
f(x) goes up 45x
g(x) goes up 140x + 8
h(x) goes up 3/4x + 12
j(x) goes up 150x
j(x) has the highest multiple to be multiplied by I believe.
