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 78 km/h, while
car B travels at a constant speed of 88 km/h.
How far is Car A from school 2 h later?
Answer in units of km
To determine how far Car A is from the school 2 hours later, we need to calculate the distance it has traveled using its constant speed.
The formula to calculate distance is:
Distance = Speed × Time
Car A is traveling at a constant speed of 78 km/h, and it has been 2 hours since it left the school. So we can plug these values into the formula:
Distance = 78 km/h × 2 hours
To get the actual distance, we multiply the speed (78 km/h) by the time (2 hours):
Distance = 78 km/h × 2 hours = 156 km
Therefore, Car A is 156 km away from the school 2 hours later.
