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?
Using Equation 14:
s = (52 miles/hour) (2 ½ hours)
s= 130 miles
t = s/vav
t = 1430 miles/650 (miles/hour)
t = 2.2 hours
