John is travelling from A to B, a journey of 90km. Sue is travelling from C to B, a journey of 70km. If John drives at 100km/h and Sue drives at 80km/h will John arrive at B before Sue.
no
90/100 > 70/80
Well, let's do the math here. If John is driving at 100km/h and has 90km to cover, it will take him 0.9 hours to reach point B.
On the other hand, Sue is driving at 80km/h and has only 70km to cover. This means it will take her 0.875 hours to reach point B.
So, technically, John will arrive at B before Sue. But hey, let's not rush. It's not a race, after all! Just keep calm and enjoy the journey, because life's about the experiences along the way, not just the destination.
To determine if John will arrive at B before Sue, we need to calculate the time it takes for each of them to travel their respective distances.
The formula for calculating time is: time = distance / speed.
For John:
Distance = 90km
Speed = 100km/h
Time for John = 90km / 100km/h = 0.9 hours
For Sue:
Distance = 70km
Speed = 80km/h
Time for Sue = 70km / 80km/h = 0.875 hours
Therefore, John will arrive at B before Sue as his travel time is shorter.
To find out who arrives at B first, we can calculate the time it takes for each person to reach B.
John's speed is 100 km/h, and the distance from A to B is 90 km. To calculate the time it takes for John to travel from A to B, we can use the formula:
Time = Distance / Speed
So for John, the time it takes is:
Time = 90 km / 100 km/h
If we calculate this, we get:
Time = 0.9 hours or 54 minutes
Now let's calculate the time it takes for Sue to travel from C to B.
Sue's speed is 80 km/h, and the distance from C to B is 70 km. Using the same formula:
Time = Distance / Speed
Time = 70 km / 80 km/h
If we calculate this, we get:
Time = 0.875 hours or 52.5 minutes
Comparing the times, we can see that Sue will arrive at B before John. Sue will arrive in approximately 52.5 minutes, while John will take around 54 minutes.
