Answer:
0.82 m/s^2
Step-by-step explanation:
Given data
initial velocity=20m/s
Final velocity= 30m/s
Time = 12.2s
Applying the formula
a= v-u/t
a= 30-20/12.2
a= 10/12.2
a= 0.819
a=0.82 m/s^2
Answer:
Step-by-step explanation:
22 liters of petrol to travel 259.6 km
1litres will travel 259.6/22 km
1litres will travel 11.8km
:2013.2km needs 2013.2/11.8litre
:2013.2km needs 170.61litres
And 1 liter of petrol costs $ 1.99
So 742.88 litres will cost $1.99×170.61
= $339.51
