00:00:00.760 --> 00:00:11.200
A car is travelling at 40 miles per hour and a train is travelling at 32 miles per hour in the same direction.
00:00:11.640 --> 00:00:17.640
How much farther than the train will the car have travelled after two hours?
00:00:18.280 --> 00:00:20.240
We have a car and a train.
00:00:20.840 --> 00:00:30.000
The car is travelling at 40 miles per hour and the train is travelling at 32 miles per hour.
00:00:30.280 --> 00:00:35.840
We need to compare how far they’ve gone after two hours.
00:00:36.320 --> 00:00:44.920
To find out how far each vehicle travelled in two hours, we’ll need to take their speed and multiply that by the time that they were travelling.
00:00:45.120 --> 00:00:54.080
And that will give us the distance: 40 miles per hour times two hours equals 80 miles.
00:00:54.640 --> 00:00:59.200
After two hours, the car has gone 80 miles.
00:00:59.880 --> 00:01:08.120
Now, I need to multiply 32 by two: 32 times two equals 64.
00:01:08.880 --> 00:01:13.960
After two hours, the train had travelled 64 miles.
00:01:14.440 --> 00:01:20.080
Now, we need to know how much farther did the car go than the train.
00:01:20.760 --> 00:01:34.160
We can find that by subtracting the distance the train went from the distance the car went: 80 miles minus 64 miles.
00:01:34.160 --> 00:01:37.040
We can’t subtract four from zero.
00:01:37.040 --> 00:01:40.160
So we borrow from our tens place.
00:01:40.400 --> 00:01:44.800
Now we have seven tens and ten ones.
00:01:45.320 --> 00:01:52.240
10 minus four equals six and seven minus six equals one.
00:01:52.920 --> 00:02:00.000
The car went 16 miles further than the train in the two hours.
00:02:00.680 --> 00:02:06.240
The car travelled 16 miles further than the train.
