The cyclist completes the 3600 m long route in 12 minutes. Calculate its speed in km/h. - Tourist average speed
A tourist moving at the same pace completes a 21-kilometer hike in 4 hours, taking a 30-minute break. Calculate the average speed of tourists. - Feet to miles
A student runs 2640 feet. If the student runs an additional 7920 feet, how many total miles does the student run? - Aircraft Carrier Acceleration
The runway of the aircraft on the mother ship is 49 m long. Calculate the aircraft's acceleration so that its speed when leaving the ejection device reaches 252 km/h. - Two trains
Through the bridge, long l = 240 m, the train passes through the constant speed at time t1 = 21 s. A train running along the traffic lights at the edge of the bridge passes the same speed at t2 = 9 s. a) What speed v did the train go? b) How long did a tr - Temperature and volume
The pool with a length of l = 50 m and a width of s = 15 m has a depth of h1 = 1.2 m at the shallowest part of the wall. The depth then gradually increases to a depth of h2 = 1.5 m in the middle of the pool. = 4.5 m walls in the deepest part of the pool. - Flooring a room
