Mathematics
1 answer:
olasank [31]2 years ago

Answer: <em>I would tell you the exact answer if I could, but I can’t because I can see it well, as it’s on its side and I’m on pc. But to find the mean/average, add all of the numbers up, then divide it by the amount of numbers you added. Like for instance, 20.1 and 22. The average would be 42.1 divided by 2. (21.05)</em>

A train has 6 identical passenger cars that are each 18 m long.
Gnesinka [82]

Answer:

59m

Step-by-step explanation:

No of passenger cars in the train = 6

length of each passenger cars = 18m

total length of 6 passenger cars = 18 * 6 = 108 m

length of caboose = 10m

total length of train when caboose is included = 108 m + 10 m = 118m

_____________________________________________

Let the length of truck be X m

given that length of train is twice of length of truck = 2*X

but length of train as found above is 118 m

this implies

2X = 118

X = 118/2 = 59m

Therefore length of truck is 59m
