00:00:01.170 --> 00:00:09.840
An athlete in training cycles fifteen miles per hour for three hours and walks at three miles per hour for another three hours.
00:00:10.190 --> 00:00:12.640
How far did the athlete travel in total?
00:00:14.810 --> 00:00:18.780
Our athlete is doing two things: cycling and walking.
00:00:20.440 --> 00:00:24.600
And we wanna know how far the athlete travelled in total.
00:00:26.590 --> 00:00:32.830
This means we need to add the distance travelled cycling and the distance travelled walking.
00:00:34.340 --> 00:00:45.390
Here’s the breakdown: cycling, the athlete went fifteen miles per hour for three hours and walking, three miles per hour for three hours.
00:00:46.600 --> 00:00:58.160
Fifteen miles per hour means that every hour the cyclist went fifteen miles and our cyclist went for three hours.
00:00:59.840 --> 00:01:10.260
To find out how far our cyclist went, we need to take the speed fifteen miles per hour and multiply it by the three hours he was cycling.
00:01:12.480 --> 00:01:21.810
The athlete training cycled forty-five miles, but we also need to calculate how far the athlete walked.
00:01:22.880 --> 00:01:31.910
The process will still be the same; we’ll take the speed that the athlete was walking and multiply it by the time that they walked.
00:01:32.790 --> 00:01:38.020
In this case, the athlete during training walked at three miles per hour for three hours.
00:01:38.070 --> 00:01:40.160
We multiply three times three.
00:01:41.410 --> 00:01:45.360
This tells us that the walking distance was nine miles.
00:01:46.690 --> 00:01:51.030
When we add forty-five plus nine, we get fifty-four.
00:01:52.420 --> 00:01:54.370
Don’t forget to add in the units.
00:01:54.500 --> 00:01:57.770
Here, we’re talking about fifty-four miles.
00:01:58.830 --> 00:02:01.910
How far did the athlete travel in total?
00:02:02.160 --> 00:02:03.950
Fifty-four miles.
