(120 km/hour) x (1/2 hour) = 60 km
t= 30min x 120km/hr = 60km
60000 meters
it is big buts
30 miles per hour is equal to 30 x 5280 = 158400 feet per hour. Three minutes is equal to one twentieth of an hour, therefore, you would travel 158000 x 0.05 = 7900 feet.
800kph
1 min is 60 seconds. So 2 min is 120 seconds. half a minute is 30 seconds. so 30 + 120 = 150.
Initial (average) speed = distance/time = 0.3 m / 1 min = 0.3 m/min If it triples its speed every minute: for the second minute it walks at 3 × 0.3m/min for the third minute it walks at 3² × 0.3 m/min for the nth minute it walks at 3ⁿ⁻¹ × 0.3 m/min → for the 7th minute it "walks" at 3⁷⁻¹ × 0.3 m/min = 3⁶ × 0.3 m/min (approx 13 km/h or 8 mph; we generally walk at 2 to 3 mph) → distance = speed × time → distance in 7th minute = 3⁶ × 0.3 m/min × 1 min = 3⁶ × 0.3 m = 218.7 m
60 mins = 1 hr → 24 min = 24 min ÷ 60 min/hr = 2/5 hr distance = time × speed → distance = 24 min × 55 mph → distance = 2/5 hr × 55 mph = 22 miles.
30 min = half an hour (60/2) so half of 120 km = 60 km
60 km.
The measure of 120 km is not a measure of velocity, so that the question is wrongly formulated. I assume that the right measure for velocity is 120 km/h. In this case in 3 min (that are 1/20 of an hour) the considered object travels 6 km.
I am going to assume you meant a constant speed of 1.5km/min. speed = distance/time distance = speed x time = 1.5km/min x 5.0min = 7.5km
Without going into all the fine points about the difference between speed and velocity, speed is generally assumed to be the distance travelled in a unit of time. As an example if you travel 120 feet in 60 minutes you travel at a speed of 120 ft/60 min = 2 ft/min. The assumption (looking at the answer) is that you travelled at the same rate every minute. However in the real world you may have gone 119 feet in 1 minute and spent the remaining 59 minutes traveling the last foot. Spped is therefor the average rate you conered the distance in the total time elapsed.
2 hrs = 120 min 120* 80% = 120 * .8 = 96 96 min = 1hr 36 min
It depends upon the speed or velocity of the car for e.g. if speed is 100km/min then Distance = speed X time i.e. D= 100X90= 9000km
The average gate to gate time is 1 hr 24 min; flight time is 56 min; the distance traveled, approximately 420 miles.
Average speed is simply the total distance traveled over the time taken to travel that distance, then you change the fraction to equal distance over 1 hour, 1 min, 1 sec, ect.
It matters how fast you're going. 60 miles per hour= 5620 min 120 mph=2810 min 240 mph=1405 min
3.0Km is a distance, not a measure of time. It depend on how fast you are going.
1 hr 51 min.
