Question from Josie, a student: At 9:00 a.m. a truck leaves the truck yard and travels west at a rate of 45 mi/hr. At 11:00 a.m., a second truck leaves along the same route, travelling at 60 mi/hr. When will the second truck catch up to the first? |
Hello,
If the first truck is moving at 45 miles/hr then how far is it from the second truck after two hours?
The second truck is travelling 15 miles/hr faster than the first, therefore the time it takes to catch up to the first truck is determined by this speed and their initial distance apart.
How long does it take to travel that distance if you travel at 15
miles/hr?
