tortoises move at a phenomenally low speed- about 0.17 mph. How many minutes would it take for a tortoise to move the length of a football field(100yds)?

Question

I'm learning about rate of change and I'm stuck on this question.

Answer 1

0.17 miles per hour = 0.17 miles per hour * 5280 feet/mile = 897.6 feet per hour

because 1 mile = 5280, so 0.17 miles = 897.6 feet

 

100 yards = 300 feet.

 

Distance = rate x time

 

time = distance/rate =   300 feet / 897.6 feet per hour = 0.3342246 hours

 

1 hour = 60 minutes , so it will take the turtle 0.3342246 x 60 minutes which is just over 20 minutes
