Find their gradients using the change in y coords divided by the change in x coords. once you have the gradients (or slopes), multiply them by eachother - if the product is (-1) then theyre perpdendicular, if not, they are either parallel or intersect at a point
Time for first plane = 625 / 250
= 2.5 hours
after 1.25 hours
boeing 747 takes 1.25 hours (2.5 - 1.25) to arrive at the same location at the same time
so, speed = distance / time
= 625 / 1.25
= 500
the average speed of the boeing 747 is 500 mph
Answer:
I believe this is the correct answer. e = 16
11 9/10 First you have to add 10 3/5 and 12 1/2. You get 22 11/10. That is an improper fraction. There are one 10 in 11. So you add 1 1/10 to 22. You get 23 1/10. Now you have to subtract 23 1/10 and 35. You get 11 9/10
