A train travels 240 km in 3 hours and 450 km in 5 hours.find the average speed of train.

Answer/Solution

86 kmph

Steps/Work

As we know that Speed = Distance / Time
for average speed = Total Distance / Total Time Taken
Thus, Total Distance = 240 + 450 = 690 km
Thus, Total Speed = 8 hrs
or,Average Speed = 690/8
or, 86kmph.

A train travels km in hours and km in hours. Find the average speed of train.

Calculated Answer

86.25

Step by Step Solution

In order to solve problem, you must evaluate (n₀ + n₂) / (n₁ + n₃).

n₀ =	240
n₁ =	3
n₂ =	450
n₃ =	5

(n₀ + n₂) / (n₁ + n₃)
Evaluate n₀ + n₂ = 690
690 / (n₁ + n₃)
Evaluate n₁ + n₃ = 8
690 / 8
Evaluate 690 / 8 = 86.25
86.25
The answer to the problem and the result of (n₀ + n₂) / (n₁ + n₃) is 86.25
