Answer:

a) 17.88 m/s

b) 12.34 m/s

Step-by-step explanation:

Given:

Total time time taken to reach the cottage = 4 hours and 28 minutes

= 4 × 60 + 28 = 268 minutes

= 268 × 60 = 16080 seconds

Total distance covered = 178.7 miles

also,

1 miles = 1.609344 km

thus,

178.7 miles = 178.7 × 1.609344 km = 287.5897728 Km

also,

1 Km = 1000 m

287.5897728 Km = 287.5897728 × 1000 = 287589.7728 m

Total displacement = 123.3 miles = 123.3 × 1.609344 km = 198432.1152 m

Now,

a) Speed = $\frac{\textup{Total distance}}{\textup{Total time}}$

Speed = $\frac{\textup{287589.7728}}{\textup{16080}}$

Speed = 17.88 m/s

b) Velocity = $\frac{\textup{Total displacement }}{\textup{Total time}}$

Velocity = $\frac{\textup{198432.1152}}{\textup{16080}}$

Velocity = 12.34 m/s
