The speed of Issam is 4 2/5 km/hr
The speed of Issam is as known as the rate of change. The formula for calculating speed is expressed as;
Speed = Distance/Time
Given the following parameters
distance = 6 3/5km
Time = 1 1/2 hour
Substitute the given parameters
Speed = (6 3/5)/(1 1/2)
Speed = (33/5)/(3/2)
Speed = 33/5 * 2/3
Speed = 22/5
Speed = 4 2/5 km/hr
Hence the speed of Issam is 4 2/5 km/hr
