What is the speed of an object if it goes 20 meter in 4 seconds?
Speed = Distance/Time = 5 metres per second
What does per second per second mean?
Per second per second or (/s/s) refers to the rate of acceleration. If you are standing still and you increase your speed at a rate of 5 feet per second per second that means after 1 second you'll be moving at 5 feet per second, after two seconds you'll be moving at 10 feet per second, after three seconds you'll be moving at 15 feet per second, and so on. Every second that goes by, 5 more feet per second will be added to your speed. So 5ft/s/s is a rate of acceleration. An easier example to understand, instead of per second per second, is per hour per second. If you are in a car that is standing still and you increase your speed at a rate of 5 miles per hour per second that means after 1 second you'll be traveling at 5 miles per hour. After 2 seconds your speed will have reached 10 mph. After 10 seconds you'll be traveling at 50mph. Each second that goes by you add 5mph to the speed.
How fast will a train travel if it goes 4 miles in 4 minutes?
60 miles an hour.
What is the acceleration of a car that goes from 32 meters per second to 96 meters per second in 8 seconds?
Acceleration = (change in speed) divided by (time for the change)Acceleration = (96 - 32) / 8 = 64/8 = 8 meters per second2
A bacteria doubles every 30 seconds how many after an hour?
I am not sure how realistic "every 30 seconds" is, but here goes.30 seconds is 1/2 minute, so there are 120 doublings in an hour. The answer, therefore, is 2120, or about 1.3 x 1036. (Assuming the "30 seconds" is realistic, it is not realistic to assume that there will be enough food for the bacterias to double this far.)I am not sure how realistic "every 30 seconds" is, but here goes.30 seconds is 1/2 minute, so there are 120 doublings in an hour.

What is the average acceleration of a care that goes from rest to 60 mph in 7 seconds in feet per second?
the car goes from 0 miles in an hour to 60 miles in an hour over 7 seconds this can be changed to minuets (60 minuets in an hour) the car goes from 0 miles in a minuet to 1 mile in a minuet over 7 seconds this can be changed to seconds (60 seconds in a minuet) the car goes from 0 miles in a second to 1/60 miles in a minuet over 7 seconds which then can be changed to feet (5280 feet in a mile) the car goes from 0 feet in a second to 5280/60 feet in a second over 7 seconds this can be simplified the car goes from 0 feet in a second to 88 feet in a second over 7 seconds now lets divide everything by 7 the car goes from 0 feet in a second to 12.57 feet in a second over 1 seconds so are answer is... the car accelerate from 0 to 12.57 feet per second in 1 second

How long does it take to drive 95 miles?
Depends on what your average speed is, if you average 95, then it takes you 1 hour. If you average 47.5, then it takes 2 hours and so it goes on.
