A car was driving for 4 hours and covered 224 miles. A high-speed train is ten times as fast as this car. Find the train's speed.

The speed of the train is 560 MPH.

Step-by-step explanation:

The car's speed can be detemined  by Distance / Time. This would mean we would have to do 224 / 4, which would equal 56.

Now, all we have to do is mulitply 56 by 10. This would equal 560.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
