Answer: b. 36km Step-by-step explanation: Distance=S=10m Time=t=1s Time=t=1sSpeed=V=? Formula S=Vt Solution S=Vt V=S/t V=10/1 V=10ms^-1 In kilometres, V= 10/1000 V=0.01km For per hour, since 1hr = 60×60 =3600s Therefore, 0.01km × 3600s 36km Reply
Answer: (a)30km Step-by-step explanation: A Car covers a distance of 10m in 1s, speed of car in km/hr is 30. Just Multiply 10m/1s with 1000m/3600s I Hope This Might Help You Dear Reply
Answer:
b. 36km
Step-by-step explanation:
Distance=S=10m
Time=t=1s
Time=t=1sSpeed=V=?
Formula
S=Vt
Solution
S=Vt
V=S/t
V=10/1
V=10ms^-1
In kilometres,
V= 10/1000
V=0.01km
For per hour,
since 1hr = 60×60 =3600s
Therefore, 0.01km × 3600s
36km
