x will be the time in hours, so your equation is 55x+48x=49
You can add the like terms together to get 103x=49
You can divide by 103 to get x=49/103, or about 0.4757281 hours, or 28 minutes and 32.62116 seconds.

It depends upon how long it travels for. Distance = speed * time So if the car travels at 60 mph for 2 hours, the distance is 60 mph * 2 hours = 120 miles But if the car travels at 60 mph for 30 minutes (0.5 hours), the distance is 60 mph * 0.5 hours = 30 miles.
Answer:3 1/3 hours or 3 hours and 20 minutesSolution:distance = velocity x timethe distance travelled by the first cyclist = 15 x timethe distance travelled by the second cyclist = 12 x timethe difference distance = 15 x time - 12 x timethis difference will be 10 miles when15 x time - 12 x time = 103 x time = 10time = 10/3 = 3 1/3 hours= 3 hours and 20 minutes.

If a car travels between two towns that are 80 miles apart in 2 hours, they travel at a rate of 40 miles per hour.
We'll assume they start out at the same time, although the question doesn't say that.Kim's lead over Alex grows at (12 - 8) = 4 mph.After 6 hours, they're (6 x 4) = 24 miles apart.
depends on the direction of the planes if they are going in opposite directions it will take one and a half hours. If they are going in the same direction, it will take ten and a half hours This assumes they fly in a straight line
Going in opposite directions, they separate at the rate of (90 + 120) = 210 miles per hour.They are 735 miles apart after (735/210) = 3.5 hours.
If an object moves in the same direction and at a constant speed for 4 hours, then the distance it travels will be equal to speed multiplied by time. The object's velocity will remain constant, and its displacement will be in the same direction as its motion.

The velocity is 83 miles per hour in some, unspecified, direction. Remember, velocity is a vector, so the direction needs to be specified.
64,800 seconds. this also depends on how fast you are traveling and what direction you are going.
