As the train’s engineer, Erin guided the train on a 64 mi run, which took 1.7 h. She then stopped on a side rail to let a second train pass. She then continued another 80 mi, which took 1.9 h.What was the train’s average speed for the entire run?

Answers

$(144 miles)/(3.6 hours)= 40 (m)/(h)$ Let's calculate how many miles the train has passed in total:
64+80=144 miles

let's also calculate the complete time: (we can ignore the waiting time here, since they also didn't move during this time:

1.7h+1.9h=3.6 hours.

And now we only need to divide the distance per time:

So the correct answer is 40 miles per hour!

a skateboard company is putting together boards and wheels to make skateboards. the company has a box of 36 boards. they need 4 times as many wheels as boards.wheels come in a pack of 20. how many packs of wheels should the company order ?

Answers

If you multiply 36 by four since there are 4 wheels for skateboard
you will get 144. That number is the total number of wheels you need to order and since they come in packs of 20 what you need to do is divide 144 by 20 and you will get 7.2. So obviously you can't order 7.20 packs of wheels so this means that 8 packs of wheels must be bought in order to ensure that all of the skateboards get wheels on them.
The answer is 8.

20% of 50 is what number

PLEASE HELP

Answers

To find a percentage, multiply the number by the percentage as a decimal. 20% as a decimal is .2.
50 times .2 is 10
50×.2=x
50×.2 = 10
10=10

20% of 50 is 10!

To get 20% of a question you would have to be able to divide by 5 so 50/5=10. So the answer is 10. Hope this helped.
