Answer:
Average speed = 0.35 m/s
Explanation:
Given the following data;
Distance = 1.3 Km
Time = 62 minutes
To find the average speed in m/s;
First of all, we would convert the quantities to their standard unit (S.I) of measurement;
Conversion:
1.3 kilometres to meters = 1.3 * 1000 = 1300 meters
For time;
1 minute = 60 seconds
62 minutes = X
Cross-multiplying, we have;
X = 62 * 60
X = 3720 seconds
Now, we can calculate the average speed in m/s using the formula;


Average speed = 0.35 m/s
193080N
Explanation:
Given parameters:
Mass of the box = 10kg
Acceleration = 12miles per second
Unknown:
Force on the box = ?
Solution:
The force acting on the box is function of the mass and acceleration of the box.
Force = mass x acceleration
Now we need to convert the given acceleration to m/s
1000m = 1km
1.609km = 1miles
x
x 
= 19308m/s
Force on box = 10 x 19308 = 193080N
