A passenger traub keaves a depot 1.5 hours after a freight train leaves the same depot. The passenger train is travleing 18 mph
skelet666 [1.2K]

Answer:

Speed of passenger train=18+30=48 mph

Speed of freight train=30 mph

Step-by-step explanation:

Let x be the speed of freight train.

Speed of passenger train=x+18 mph

Time taken by freight train=1.5+2.5=4 hrs

Time taken by passenger train to overtake the freight train=2.5 hrs

Distance=Speed\times time

By using this formula

Distance traveled by passenger train=2.5(x+18)  miles

Distance traveled freight train=4x

According to question

2.5(x+18)=4x

2.5 x+45=4x

45=4x-2.5 x

45=1.5 x

x=\frac{45}{1.5}=30

Speed of freight train=30 mph

Speed of passenger train=18+30=48 mph

Write the equation in standard form of the circle with radius 5 and center 0,3
EleoNora [17]
The equation of a circle is (x-h)²+(y-k)²=r², with h being the x value in the center, k being the y value, and r being the radius. x and y can stay variables, so we can plug numbers in to get (x-0)²+(y-3)²=5²=25=x²+(y-3)²
