Question 143648
there are 2 missiles, one is going 9000 per hour, the other is going 2100 per hour they started off at 1317 miles apart, how many miles apart will they be 1 minute before they touch?
:
We don't care how far they were apart at the start;
:
We want the relative speed to each other:
9000 + 2100 = 11,100 mph
:
Distance traveled in 1 min at that speed:
{{{11100/60}}} = 185 mi
