Nicky and Cristina begin running a race at the same time, though Nicky begins the race at the same time, though Nicky begins the race 36 meters ahead of Cristina. If Cristina runs at a pace of 5 meters per second and Nicky runs at a pace of only 3 meters per second, how many seconds will Nicky have run before Cristina catches up to him?

Nicky and Cristina are running a 1,000 meter race. Because Cristina is faster than Nicky, she gives him a 12 - second head start. If Cristina runs at a pace of 5 meters per second and Nicky runs at a pace of only 3 meters per second, how many seconds will Nicky have run before Cristina catches up to him?

During their daily training race, Carl has to stop to tie his shoes . Melissa, whose shoes are Velcro , continues to run and gets 20 feet ahead of Carl . Melissa is running at a constant rate of 8 feet per second , and Carl starts running at a constant rate of 9.2 feet per second to catch up to Melissa . Which of the following equations , when solved for s, gives the number of seconds Carl will take to catch up to Melissa ?

A can run 1 km in 2 min 20 seconds and B can run the same distance in 3 min. What is the distance travelled by B in the same time as A travels, when they start simultaneously in the race of 4.5 km.

As shown in the figure above, a lifeguard sees a struggling swimmer who is 40 feet from the beach. The lifeguard runs 60 feets along the edge of the water at a speed of 12 feet per second. He pauses for 1 seconds to locate the swimmer again, and then dives into the water and swims along a diagonal path to the swimmer at a speed of 5 feet per second. How many seconds go by between the time the lifeguard sees the struggling swimmer and the times he reaches the swimmer?

A military band was marching on a street in the same direction as the normal traffic flow. A motorist was approching the band from behind in his car just at the moment when they were playing the musical note A (frequency 440 Hz ) in unison. The same band' performance was also simultaneously being broad live on the ratio from a stationary microphone which was situated on the sidewalk just ahead of the band. The motorist noticed that the combination of the direct sound coming from the band ahead of the band brodcast produced discernible beats. Timing the beats, he counted 4 beats in 3 seconds. He noted from the speedmeter that his car was travelling at 18 kilometers per hour. Calculate the speed in meters per seconds at which the band was marching assuming that the speed of sound on that day was 330 ms^(-1) . (It was a very cold day)

In a 100m race: A runs at 8km per hour.If A gives B a start of 5m and still beats him by 15 seconds: what is Bs speed.

In a potato race, a bucket is placed at the starting point, which is 5m from the first potato, and the other potatoes are placed 3m apart in a straight line. There are ten potatoes in the line (fig.). A competitor starts from the bucket, picks up the nearest potato, runs back with it, drops it in the bucket, runs back to pick up the nest potato, runs to the bucket to drop it in, and she continues in the same way until all the potatoes are in the bucket. What is the total distance the competitor has to run ? [Hint : To pick up the first potato and the second potato, the total distance (in metres) run by a competitor is 2 xx 5 + 2 xx (5 + 3) ]
