The speed of car is 106.67 miles per hour
To solve problems involving speed and distance we are required to first find speed or distance travelled in an hourly timeframe
It is given that car takes 4 hours to cover the distance at a speed of 40 miles per hour
Therefore, total distance travelled by the car= speed x time
= 40 miles per hour x 4 hour
=160 miles
We are required to find the speed of the car if the distance is to be covered in 1.5 hours
We are required to find the speed by the formula speed= Distance/time
distance= 160 miles time = 1.5 hour
speed= 160/1.5=106.666=106.67 miles per hour
Hence the speed is 106.67 miles per hour

Answer:
Move the opposite direction ( at a lesser magnitude of velocity)
Explanation:
Here is the highly detailed, arcane, complex, technical form of Ohm's Law that is needed in order to answer this question ===> V = I · R .
Voltage = (current) x (resistance)
Voltage = (2 Ampere) x (8 Ω)
<em>Voltage = 16 volts</em>
Explanation:
Using Newtons second law on each block
F = m*a
Block 1
Block 2
Block 3
Solving Eq1,2,3 simultaneously
Divide 1 and 2
Put Eq 4 into Eq3
Put Eq 5 into Eq2 and solve for a
Substitute back in Eq2 and use Eq4 and solve for T2 & T1
