what stapel said you should do is correct im just going to show you a tip on how to figure out the equations for distance,time, and speed questions that my math teacher taught me. i cant draw it on here so your going to have to figure it out by my discription. make a pyramid. split it up in the middle horizontally, NOT vertically. so on the top half of the pyramid(it will have the point at the top)put a letter "D" in the middle. then look at the bottom part of the pyramid(souldnt have the point at the top)and split it into 2 sections *vertically* so your pyramid will have 3 sections in total. one on the top half and two on the bottom half...on the bottom half on the left section put a letter"s" and on the right side put a letter"t" ....alright thats it for drawing ...now the "d" stands for distance, the "s" for speed and the "t" for time. now how this works is if you want to find the speed, cover up the "s" so you can only see the "d" and "t" it should look kinda like this D
---
t
and it looks like a division sign so when you want to find the speed you go distance divided by time. when you want to find the time, cover up the "t" and you will have something like this d
----
s
and so you will dived the distance by speed you will get the time..when you want to get the distance, you cover up the "d" and are left with
"s" with a "t" beside each other with a line seperating them meaning to multiply, so speed x time will give you distance. and vise-versa(time x speed gives you distance) ..
so for your question you have the speed:60km/h
distance:528 feet
so you need to find you how to get the time...so you cover up the "t" in your pyramid, and get that distance divided by speed will give you time...just remember to change your units and everything!!!i hope this helped and isnt too confusing
