1.If a soldier marched at 3 miles an hour,how many feet did he move in a minute?

3miles/hour
=3X5280feet/60minutes
=15840feet/60minutes
=(15840/60)feet/minute
=264feet/minute

Therefore he moved 264 feet in a minute.

Note: Answer should be in feet/minute not minute.

1 miles = 5280 feet

Say, soldier speed = 3 x 5280 = 15840 feet/hr

= 15840 / 60 = 264 feet/min

Answer: 264 minutes
