Question

a train travels 75 kilometers in 5 hours and then 88 kilometers in 2 hours ? what is average speed

Answer 1

29.5 km/h is the answer you are looking for because 75 km in 5 hours is 15 km/h and 88km in 2 hours is 44 km/hr so if you add 15 and 44 and divide the answer, which is 59, by 2 because there are two numbers you will get 29.5 

Answer 2

(total distance) / (total time)

= 163 kilometers / 7 hours

= 23.3 km/hour. (rounded)
