Let say for every 5 s of time interval the speed will remain constant
so it is given as
v(mi/h) 16 21 23 26 33 30 28
now we have to convert the speed into ft/s as it is given that 1 mi/h = 5280/3600 ft/s
so here we will have
v(ft/s) 23.5 30.8 33.73 38.13 48.4 44 41.1
now for each interval of 5 s we will have to find the distance cover for above interval of time
so here it will cover 1298.1 ft distance in 30 s interval of time

Answer:
Explanation:
Average speed= Total distance/ Total time
Initial reading= 2200
final reading= 3800
total distance= Final reading -initial reading = 3800-2200 = 1600 km
total time= 20 hrs
Average speed= 1600/20
= 80 km/hr
CONVERTING km/hr TO m/s
To convert km/hr to m/s just multiply
Recall that,
1000m = 1 km
60 secs = 1 min
60 mins = 1 hr
( 80 × 1000 ) meters / ( 60×60 ) secs
80000m / 3600s
= 22.22m/s
