The odometer of a car is 12345km when the clock shows the time 8:30am what is the distance moved by the car if at 8:50am the odometer reading has changed to12543km calculate the speed of the car in km per minute and hour also

D₈₋₃₀ₐₘ=12345km
D₈₋₅₀ₐₘ=12543 km
the distance covered by the car from 8.30 am to 8.50am(D₃) =D₈₋₅₀ₐₘ-D₈₋₃₀ₐₘ
D₃=12543-12345
D₃=198km
time in minutes (t₁)=(8×60)+50-(8×60)-30
t₁=20mins
time in hours (t₂)= t₁/60
t₂=20/60
t₂=1/3
speed in km/min(sₘ)=D₃/t₁
sₘ=198/20
sₘ=9.9km/m
speed in km/h(sₕ)=D₃/t₂
sₕ=198/(1/3)
sₕ=594km/h
