Answer:

3.8 m/s

Step-by-step explanation:

Momentum is the product of mass and velocity hence

Momentum=mv where m is mass and v is the velocity of an object

Making v the subject of the formula then

$v=\frac {momentum}{m}$

Substituting 1710 kgm/s for momentum and 450 Kg for mass we obtain

$v=\frac {1710 Kgm/s}{450 Kg}=3.8 m/s$

Hence the speed of dogsled team is 3.8 m/s
