A train leaves at 0836 and arrives at 1057. It travelled at an average speed of 85 km/h. How far did it travel?

199.75km

Step-by-step explanation:

Step one:

given data

We are told that the time of travel is from

8:36- to 10:57

which is 2 hours 21 minutes

Hence the time taken is 2.35 hours

the speed is 85km/h

Step two:

From the expression

speed= distance/time

85= distance/2.35

distance= 85*2.35

distance= 199.75km

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
