Question

a bus moves 30 kilometre in 30 minutes and the next 30 km in 40 minutes. Calculate the average speed for the entire J journey​

Answer 1

Answer:

1.16km in a minute

Explanation:

total distance covered-60

time taken-70

so 70/60 (total distance covered by total time taken)

=1.16

Answer 2

Explanation:

the distance between first journey is

average speed = total distance/total time taken

=30/30

=1

In the second journey

average speed = total distance/total time taken

=30/40

=0.75

Now add both the speeds

=1+.75

=1.75
