You drive your car for 2.0 h at 40.0 km/h then for 2.0 h at 60.0 km/h what is your average velocity?

Verdich [7]

In order to calculate velocity, we'd need to know the straight-line distance between the start and the finish, and we'd also need the direction of that line. The best we can do with the information given in the question is calculate the average SPEED.

Average speed = (total distance covered) / (time to cover the distance).

Distance covered in the first 2 hours = (2 hr) x (40 km/hr) = 80 km.
Distance covered in the second 2 hours = (2 hr) x (60 km/hr) = 120 km.

Total distance covered = (80 + 120) = 200 km
Time to cover the distance = (2 + 2) = 4 hours

Average speed = (200 km) / (4 hours) = 50 km/hour

An airplane flies with a constant speed of 560 miles per hour. How long will it take to travel a distance of 840 miles?

Vilka [71]

Answer:

t = 1.5 hours

Explanation:

Given that,

Speed of an airplane, v = 560 miles per hour

Distance, d = 840 miles

We need to find the time taken to cover a distance of 840 miles.

$v=\drac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{840}{560}\\\\t=1.5\ h$
