1. rearrange the formula d = v*t and solve for velocity (or average speed). a car travels 25 km in 30 min. what was the car’s average speed?

V= d/t, The answer is 0.83 km/m.

Assuming the object is on earth the objects weight would be equal to its mass multiplied by the gravitational field constant

mass=22kg
g=9.80665N/kg

weight=(22 kg) (9.80665 N/kg)=215.7463N

generally g is rounded to be 10 N/kg so for any question where it asks the weight given the mass just multiply by 10 and that should suffice. In this case the answer would be 220 N
