A truck leaves point A traveling 60 mph. After two hours, a car leaves point A traveling 90 mph and follows the truck's route. A t what distance from point A will the car catch up with the truck?
1 answer:
The car catches up with the truck after a distance of 360 miles from point A.
Speed is the ratio of distance travelled to total time taken . It is given by:
Speed = distance / time
For truck:
60 = d / t
d = 60t
Since the car leaves the truck after 2 hours, hence:
For the car:
90 = d/ (t - 2)
d = 90t - 180
For the truck and car to catch up:
60t = 90t - 180
30t = 180
t = 6 hours
d = 60t = 60(6) = 360 miles
The car catches up with the truck after a distance of 360 miles from point A.

Answer:
i believe its false good Sir
U just need to turn the diagram to the way you can understand it
1/6 < 1/4 so 1/6 would equal 2/12 and 1/4 would equal 3/12 so which means if you take one from each it would be 5/12 but if you took 2 from the first one it would only be 2/12 which is why you need to read correctly because THE REASON MARK IS CORRECT IS BECAUSE 5/12 IS GREATER THAN 2/12
