# A rock climber wants to know the height of a cliff. 
# You need to write a program to help him calculate. 
# He shares the below information:
# The climber measures the shadow of her friend, who is 5 feet tall and standing beside the cliff 
# He then measures the shadow of the cliff.
# If the friend's shadow is 4 feet  long and the cliff's shadow is 60 feet long, how tall is the cliff?
# Hint: Cliff_height=friend_height * cliff_shadow / friend_shadow

# Both started at 10:00am.

# But this time they both went together. 
# Here are the details of the distance travelled:
# uphillDistance travelled: 10 km
# downhillDistance travelled: 9 km
# Time taken to go up hill: 66 minutes
# Time taken to come down hill: 46 minutes
# Write a program to calculate the total distance cycled and the average speed taken.
# [Hint: You need to find the total distance, the total time and then calculate the average speed as total distance/total time]
