Tom walks at an average speed of 8km/hr. The distance [d(t)] his walks can be represented by the function d(t)=8t where t is the time in hours.
a) Calculate d(4.25) d(4.25) = 8*4.25 = 34 km. (Simply substitute t= 4.25 into the formula d(t) = 8t).
b) Calculate t if he walks a distance of 4 km. 8*t = 4 ====> t = = of on hour = 30 minutes.
