HI there !!
Time = t₁ = 2 sec
Time = t₂ = 5 sec
Total time = t₁ + t₂
= 7 sec
Distance traveled = 220 + 200 = 420 cm = 4.2 m
Speed = distance / time
= 4.2 / 7
= 0.6 m/s
Time = t₁ = 2 sec
Time = t₂ = 5 sec
Total time = t₁ + t₂
= 7 sec
Distance traveled = 220 + 200 = 420 cm = 4.2 m
Speed = distance / time
= 4.2 / 7
= 0.6 m/s
