    Question about Uniform motion

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    The fundamental formula for such problems is

    where d represents the distance covered when moving at a speed s during a length of time t.

    This formula can be solved for s or t
    (if d is in miles and t is in hours, then s has the units of miles/hour)

    Smith bicycled 45 miles going east from Durango, and Jones bicycled 70 miles. Jones averaged 5 miles per hour more than Smith, and his trip took one-half hour (1/2 hr) longer tan Smith's.
    - Write an expression for Jones' speed in terms of Smith's speed
    - Write an expression for Smith's speed
    - Write an expression for the time it takes Smith to travel 45 miles
    - Write an expression for the time it takes Jones to travel 75 miles
    - Write an expression for Jones' time in terms of Smith's time
    - Write an equation for Jones' time in terms of Smith's time
