Okay, so you have an interview at 11 .15 a .m.
00:07
And if you're leaving at 8 a .m., we want to figure out, so if you travel for 100 kilometers at 100 kilometers per hour, and then you slow down for a little while, and you're traveling at, well, you're traveling for 42 kilometers at 44 kilometers per hour.
00:48
We want to know how fast you have to travel for the rest of this trip to get there by 11, 15 a .m.
00:58
So there's a few different parts here.
01:02
So the total is 310 kilometers.
01:06
So what do we have left after we travel? the 100 minus 42, so minus 100 and minus 42, we end up with 168 kilometers left.
01:30
So this is 168 kilometers.
01:36
And also, so we've been dry.
01:40
So let's figure out how long we've driven in these first two parts here, here and here, and figure out what time it is when we get to this point.
01:53
All right.
01:54
So the first part, so, i mean, it's pretty obvious if you're driving 100 kilometers per hour and you drive 100 kilometers that you've been driving for one hour.
02:11
But just to write it out, that's 100 kilometers divided by the velocity of 100 kilometers per hour.
02:25
Equals one hour.
02:29
Oops, one hour...
