b.)58.33m/min

Step-by-step explanation:

• 3.5km/h*1000m/3600s=0.972m/sec
• b.)3.5km/h*1000m/60min

Answer 2

Answer:

m/min

Speed= 58 1/3 m/m in

Step-by-step explanation:

Distance = 17 1/2 = 17. 5 km

Time = 5 hr

(1 Km = 1000 M)

(1 hr = 60 min )

So, 17.5 turns - 175000 m

and 5 hr turns - 300 min ( 60 X 5)

Speed=Distance / Time

= 175000 / 300

= 583.3

= 58 1/3 m/min
