*Average Speed v = d/t


Distance d = v t


Time t = d/v


* remember v = average speed


Solve the following problems for average speed, distance or time. Round to tenths place:


Find the distance traveled by a car that travels with an average speed of 110 km/h for 3.5 h.

How long does it take a baseball moving with an average speed of 35 m/s to travel 18 m?

What is the average speed of a car that travels 870 km in 14.5 h?

Respuesta :

Find the distance traveled by a car that travels with an average speed of 110 km/h for 3.5 h

To solve for distance:

d = v t

d = 110 × 3.5

d = 385 km

How long does it take a baseball moving with an average speed of 35 m/s to travel 18 m?

To solve for time:

t = d/v

t = 18 / 35

t = 0.514286

t = 0.5 s

What is the average speed of a car that travels 870 km in 14.5 h?

To solve for average speed:

v = d/t

v = 870 / 14.5

v = 60 km/h
