Question

Car travels 50 kilometre in 30 minutes and then 15 kilometre in 15 minutes and 35 km in 45 minutes what is the average speed in kilometre per hour

Answer 1

Answer:

average speed = total distance/total time taken

now

total distance in this journey=50+15+35=100km

total time taken =30+45+15=90min.

average speed =100/90 km per min.

=10/9 km per min

change km per min. to km per hour

we get

200/3 km per hour
