By definition we have to:
v = d / t
Where,
v: speed
d: distance
t: time
The time in hours is given by:
t = 4 + (45/60)
t = 4.75 hours
Substituting values we have:
v = 456 / 4.75
v = 96 km / h
Answer:
the speed of the train is:
v = 96 km / h
Since there are 7 days in a week, you divide 200 and 7 to get 28.57.
You must also round to the nearest integer, so the lizards in the shows eat about 29 crickets each day.

Answer:
180
Step-by-step explanation:
87b-179+957/87
Replace b with 4
87*4-179+957/87
Evaluate 87*4=348 and 958/87=11
348-179+11=169+11=180
