Both car A and car B leave school at the same time, traveling in the same direction. Car A travels at a constant speed of 77 km/h, while car B travels at a constant speed of 89 km/h.

1. How long does it take car A to reach a gas station a distance 247 km from the school?
Answer in units of h.

2. How long does it take car B to reach the gas station?
Answer in units of h.

1. Well, car A is no turtle, that's for sure! At a zippy speed of 77 km/h, it will take a bit of time to reach the gas station 247 km away. To calculate the time it takes, we divide the distance by the speed. So, 247 km divided by 77 km/h gives us approximately 3.21 hours. So, it will take car A approximately 3.21 hours to reach the gas station.

2. Now, car B means business with its impressive speed of 89 km/h. To find out how long it takes for car B to reach the gas station, we divide the distance of 247 km by the speed of 89 km/h. After the mathematical gymnastics, we find that it will take car B approximately 2.77 hours to reach the gas station. So, car B will get there a bit faster than car A, in around 2.77 hours.

1. To find the time it takes for car A to reach the gas station, we can use the formula: time = distance / speed.

The distance is given as 247 km, and the speed of car A is given as 77 km/h. Plugging these values into the formula, we get:
Time taken by car A = 247 km / 77 km/h = 3.2078 hours (rounded to 4 decimal places)

Therefore, it takes car A approximately 3.2078 hours to reach the gas station.

2. Similarly, for car B, we can use the formula time = distance / speed.

The distance to the gas station (247 km) and the speed of car B (89 km/h) are given. Plugging these values into the formula, we get:
Time taken by car B = 247 km / 89 km/h = 2.7753 hours (rounded to 4 decimal places)

Therefore, it takes car B approximately 2.7753 hours to reach the gas station.

To find the time it takes for each car to reach the gas station, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for each car.

1. Car A:
Distance = 247 km
Speed = 77 km/h

Time = 247 km / 77 km/h
Time = 3.207792208 h

Therefore, it takes car A approximately 3.21 hours to reach the gas station.

2. Car B:
Distance = 247 km
Speed = 89 km/h

Time = 247 km / 89 km/h
Time = 2.775280899 h

Therefore, it takes car B approximately 2.78 hours to reach the gas station.

1. d = r * t = 247 km

77 * t = 247
t =

2. 89 * t = 247
