Question

An ant carries food at a speed of 1 cm/s. How long will it take the ant to carry a cookie crumb from the kitchen table to a the ant hill, a distance of 50 m? Express your answer in seconds, minutes, and hours.
Help please?

Answer 1

speed=distance/time 
time = distance/speed
Keep distance and speed in cm and cm/sec 
Meters x 100 = cm time
= 50 m X 100/ 1 = 5000 secs 
= 5000/60 mins = 83 1/3 mins 
1/3min = 20 sec.
So 83 1/3 mins 
= 1 Hr 23 Min and 20 Secs
