Problems Involving Motion - Word Problems:

How far can a car travelling at a rate of 52 miles per hour travel in 2½ hours?

Solution:

Using Equation 13:

s = vavt

s = (52 miles/hour)(2½ hours)

s = 130 miles

Example:

How long does it take a plane travelling at 650 miles per hour to go 1430 miles?

Solution:

Using Equation 14:

s = v_avt

s = (52 miles/hour) (2 ½ hours)

s= 130 miles

t = s/v_av

t = 1430 miles/650 (miles/hour)

t = 2.2 hours
