At 1:00 p.m. a car, traveling at a constant
velocity of 86 km/h toward the west, is 22 km
to the west of our school.
How far from the school will it be at 3:30
p.m.?
Answer in units of k
distance=2.5hr*86km/hr + 22km West
To find out how far the car will be from the school at 3:30 p.m., we need to calculate the distance it travels in 2.5 hours.
The car is traveling at a constant velocity of 86 km/h toward the west. Therefore, in 2.5 hours, it would have traveled a distance of:
Distance = Velocity x Time
Distance = 86 km/h x 2.5 hours
Calculating this, we get:
Distance = 215 km
So, the car will be 215 km away from the school at 3:30 p.m.
To find the distance from the school at 3:30 p.m., we need to calculate the total distance the car traveled during that time.
First, let's determine the time difference between 1:00 p.m. and 3:30 p.m.:
3 hours and 30 minutes - 1 hour = 2 hours and 30 minutes.
Next, we can use the formula: distance = velocity × time.
Given that the car is traveling at a constant velocity of 86 km/h, and the time is 2 hours and 30 minutes (or 2.5 hours), we can calculate the distance traveled:
Distance = 86 km/h × 2.5 h
Calculating this expression, we get:
Distance = 215 km.
Therefore, the car will be 215 km away from the school at 3:30 p.m.
