Question

Two cars started from the same point, at 5 am, traveling in opposite directions at 40 and 50 mph respectively. At what time will they be 450 miles apart?​

Answer 1

Answer:

5

Step-by-step explanation:

40m*5hrs = 200 miles

50m*5hrs = 250 miles

so in 5 hrs both car would have travelled 450miles.

Answer 2

From the given information, the distance between the two cars will be 40+50 miles or 90 miles.

To get the time required for the two cars to be apart by 450 miles get the equation as,

time = Total distance travelled divided by the distance travelled in 1 hour

t=  $\frac{450}{90}$

​ t=5

As the time at the start of travelling was 5am, adding the time taken will be

5hours + 5hours= 10am.

Ans : The two cars will be apart from each other by 450miles at 10am.
