A car and a bus which are 280 miles apart are driving towards each other. The car is moving at 50 mph while the bus is moving at 55 mph. How long will it take them to meet?

2.6667 hours

Step-by-step explanation:

Given that:

Distance between car and bus = 280 miles apart

What le moving towards each other ;

Speed of car = 55 mph

Speed of bus = 50 mph

Time it will take them to meet;

Time = distance / speed

Hence :

Total distance to be covered = 280 miles

Total speed = (55mph + 50 mph) = 105 mph

Hence ,

Time = 280 miles / 105 mph

Time = 2.667 hours

2 hours, (0.667 * 60 = 40.02

2 hours, 40 minutes

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
