During 5 successive 1.08 min intervals, a runner moves at the following constant speeds: 0.436 km/min, 0.220 km/min, 0.160 km/min, 0.160 km/min, and 0.320 km/min. Compute the total distance traveled and the average speed.
Accepted Solution
A:
Answer:1.4[km]Step-by-step explanation:becouse the runner are running at constat speed we just to multiplicate each velocity for the time was running for each time´s interval. 1: 0.436[km/min]*1.08[min]=0.4709[km]2: 0.220[km/min]*1.08[min]=0.238[km]3: 0.160[km/min]*1.08[min]=0.1728[km]4: 0.160[km/min]*1.08[min]=0.1728[km]5: 0.320[km/min]*1.08[min]=0.3456[km]Total distance: 1+2+3+4+5= 1.4[km]
