Answer 1

It would be 265 i think

Answer 2

Solution:

we are given that

Two trains began their trip from the same station at 8:00 a.m. One train travelled North at a rate of 44 mph and the other travelled South at a rate of 46 mph.

we have been asked to find

What time will it be when the trains are 405 miles apart?

As we know that

$Distance =Speed*Time$

Suppose they are 405 miles apart after t hours.

So using this formula we can write

$44t+46t=405\\ \\ \text{Solve for t we get}\\ \\ 90t=405\\ \\ t=\frac{405}{90}= 4.5 Hrs$

Hence they will be 405 miles apart by 8+4.5=12.5PM.
