Answer 2

Answer:

speed in km/hr will be

speed = distance ÷ time

speed (km/hr) = 80÷2 = 40km/hr

speed (m/s) = for this you have to convert 80 km to m that is 80 × 1000 = 80000 m and 2 hr in second = 2 ×60 = 120 minutes = 120 minutes × 60 =7200 seconds

speed (m/s) = 80000÷7200

= 800÷72

= 400÷36 = 200 ÷ 18 =

100 ÷ 9 m/s
