Question

A train travels a distance of 2000 km at an average speed of 120 km per hour. How long did the trip take? SHOW WORK

Answer 1

s = d/t, s = 120, d = 2000, t = ?
Input the values,
120 = 2000/t
Make t the subject of the formula by cross multiplying, Therefore,
120t = 2000
Divide both sides by 120
t = 16.7hrs  to 1 decimal place.
