Answer:
1. The speed of the truck, S = D/T.
2. The formula that connects D and T is: S = D/T.
3. The coefficient of variation, k, is the ratio of the standard deviation to the mean speed.
Step-by-step explanation:
a) The speed of a truck at a fixed speed is given as the distance covered by the truck divided by the time it takes the truck to cover the said distance. This implies that speed is a function of distance and time. However, this formula represents the mean speed. There are variations in speed.
b) If the truck covers a distance of 60 kilometers, for example, under 3 hours, we can conclude that the speed is 20 kilometers per hour (60/3) or 20 km/hr.
11:00 P.M.
Bus A would do the route 13 times
Bus B would do the route 12 times
1/16 = 10 minutes
10 minutes x 6 = 60 minutes
60 minutes = 1 hour
1/16 x 6 = 6/16
he would walk 6/16 in an hour
