What is the average speed for 5 kilometers in 25 minutes?
its 0.2 km/min. the formula for speed is S=D/T-S: speed-D: distance-T: time
What is the derivative of te(-t2)?
Use the product and chain rules: d/dt te^(-t²) = (d/dt t)e^(-t²) + t(d/dt e^(-t²)) = 1 × e^(-t²) + t × e^(-t²) × d/dt -t² = e^(-t²) (1 + t × -2t) = (1 - 2t²)e^(-t²)
What is the formula to determine time knowing speed and distance?
D = rt t = d/r r = d/t
How many hours before midnight in 3 hours?
If the time now is T hours (on a 24 hour clock), then the answer is mod(21 - T, 24) hours.
What time is 25 hours past 900 am?
There are 24 hours in 1 day, so 25 hours = 24 hours + 1 hours = 1 day + 1 hour Thus 25 hours after 09:00 am is 10:00 am on the following day.
How many hours would it take to drive 715 miles at 65 mph?
Use the formula: V=D/T Where V= Velocity D= Distance T = Time So solving for T T = D / V T = 715miles / 65 Mph T = 11 hours
If a car goes 90mph for 3 hours. how far did it get?
d=t*v d=3h(90mph) d=270 miles
What is the average speed for 5 kilometers in 25 minutes?
its 0.2 km/min. the formula for speed is S=D/T-S: speed-D: distance-T: time
How long does it take to go 1 mile going 80mph?
If my maths are right, it would take you 45 seconds... S= Speed, D= Distance, T= Time S=D/T T=D/S T=1 / 80 T= 0.0125 hours * 3600 seconds = 45 seconds Czar~
How long does 250 miles take going 70miles per hour?
Well, d(istance)=r(ate)*t(ime), so if d=250 miles and r=70 mph, t= 3.6 hours, or 3 hours and 36 minutes.
State the equation linking average speed distance moved and time taken?
speed = distance divided by time. S = d/t S(mph) = d(miles) / T(hours)
How long to travel 15 nautical miles at 12 knots?
v = d/t so... t = d/v = 15/12 = 1.25 hours or 1 hr 15 min
How long would it take to drive 500 miles at 125 mph?
4 hours because, D=ST,T=D/S substituting values, T=500/125=4 hrs.
What is the average speed of a car that speeds up from 0 miles per hour to 25 miles per hour?
If the car goes from 0 to 25 miles per hour at constant acceleration, the average speed when it reaches 25 mph will be 12.5 mph. Distance (d) traveled during time twhen starting from 0 velocity and accelerating at a constant acceleration of a: d = at²/2 Velocity (v) at time t when starting from velocity 0: v = atso the time it will take to get to 25 mph will be: t = v/a = 25(mph)/aaverage velocity will be: d/t = (at²/2)/t = at/2 = a(25mph/a)/2 = 12.5 mph
How many hours is a 2350 mile drive at 80 miles per hour?
Using the formula D/T, you get 29 hours and 22.5 minutes
How many hrs and mins in 265 mins?
4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.4 hours and 25 minutes.
How many hours would it take to do 230miles at 60mph?
R=D/T 60 = 230 /T 60T=230 T= 230/60 = 23/6 (23/6) * 60= 230 minutes 3 hours and 50 minutes
