If the bus had traveled 60 kmh faster than it actually did, the trip of 120 km would have lasted 1 hour less. Find the speed of the bus.
Answer/Solution
60 kmh
Steps/Work
Time = Distance/Speed
Difference in time = 1 hr
120/x - 120/(x + 60) = 1
Substitute the value of x from the options. --> x = 60 --> 120/60 - 120/120 = 2 - 1 = 1
