Question

A train travels at a speed of 60km/hr for 5hr and 30km/hr for 8hr.What is the average speed of the train?​

Answer 1

Answer:

we will do this:-

Step-by-step explanation:

to calculate average speed we need to take time 1 and time 2 and distance 1 and distance 2.

60 km/HR FOR 5 HR

we will find the distance by multiplying speed and time

we get 300 km

now the other:-

30 km for 8 hr

30* 8 = 240

now we will add the times and distances

so 5 + 8/ 300+ 240

we get 13/540

then we get 0.02407407407 km/hr

sorry if this is wrong. im not good at math XD

Answer 2

SOLUTION:

Distance=Speed×Time

(i) distance=60×5=300km

(ii) distance=30×8=240km

AVERAGE SPEED= total distance/total time

300+240/5+8

540/13

Answer: 41.53km/hr
