1. Find the velocity in meters per second of a swimmer who swims exactly 110 m toward the shore in 72 s.
Given: distance d = 110 m, time t = 72 s
Velocity v = d/t = 110/72 = 1.53 m/s

2. Find the ...

Solution Summary

Speed, Time and Distance are investigated. The solution is detailed and well presented. The response received a rating of "5/5" from the student who originally posted the question.

Janet drove 120 miles at x mph before 6:00 a.m. After 6:00 a.m., she increased her speed by 5 mph and drove 195 additional miles. Write a rational expression for her total traveling time. Evaluate the expression for x = 60.

Leon drove 270 miles to the lodge in the same time as Pat drove 330 miles to the lodge. If Pat drove 10 miles per hour faster than Leon, then how fast did each of them drive?

A fisherman notices that wave crests pass the bow of his anchored boat every 4.0seconds. He measures the distance between two crests to be 9.0 m. How fast are the waves traveling?
**please explain this in the simplest, least confusing way....thank you so much :)

Ryan starts jogging home at the rate of 6km/hr. After reaching Harbor Front, he begins jogging back home. Because of fatigue, his speed for the return trip decreases to 4.5km/h and takes 1 hour longer. Determine the total distance that Ryan jogged.

Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 4.0 mi/h, the time to go one mile decreases by 12 s. What was your original speed?
....... mi/h ?

A baseball diamond is a square with side 90 ft. A batter hits the ball and runs toward first base with a speed of 24 ft/s.
(a) At what rate is his distance from second base decreasing when he is halfway to first base?
(b) At what rate is his distance from third base increasing at the same moment?

Tom took 16 hours to drive the 1,000 highway miles from Chicago to Boston. He drove the first eight hours at constant speed,and then had to lower his speed considerably by 25 miles per hour for the remainder of his journey to Boston on account of construction. However, he maintained this constant lower speed for another 8 hours

A boat travels up a river a distance d and then comes back to the origin.
The maximum speed of the boat relative to the water is v. And the river has scalar speed u (u < v).
What is the minimum time for this trip?
