Answer 1

Answer:

its easy bro

Explanation:

Answer:

The average speed of bus is 45 km/h

Explanation:

Formula: time= distance/speed

A bus travels first 100 km with the speed of 50 km/h

Time taken by first route T1=100/50= 2 hours

Next 80 km with speed of 40 km/h

Time taken by second route T2= 80/40=2 hours

average speed= total distance/ total time

total time = T1+T2 = 2+2 =4 hours

total distance = 100+ 80 = 180km

avg. speed= 180/4= 45 km/hr

Substitute the value into formula to get average speed
