The Total distance traveled = 45h and The number of hours traveled = d/45.
Speed, Time, and Distance Units
Speed, distance, and time can all be expressed in one of three ways:
Time is measured in seconds (sec), minutes (min), and hours (h) (hr)
Distance in meter (m), kilometer (km), mile, and feet
Speed in (m/s, km/hr)
So, if distance = kilometer and time = hour, velocity = distance/ time; the units of speed are kilometers per hour.
The units of speed, time, and distance are self-evident; let us examine the conversions associated with these.
We know that,
Speed = Distance / time
Distance = Speed * time
Time = Distance / Speed
Given , the total distance traveled = d
Speed = 45 miles per hour
The number of hours = h
The Total distance traveled = Speed * Number of hours
≅ 45h
The number of hours traveled = Distance / Speed
≅ d / 45
∴ The Total distance traveled = 45h and The number of hours traveled = d/45.
