Calculating Speed

Given

• Distance (d) = 144 km
• Time (t) = 3 hours
• Speed (s) = ?

s = d / t

s = 144 / 3

s = 48 km/h

The variables of speed, distance and time has a correlation on one another. In finding the speed, you should divide the distance to time because speed is inversely proportional to distance and time.

Other formulas are

• d = st
• t = d / s

Verified answer

Answer:

48 km/hr

Explanation:

To get the total speed, use the formula speed(s)= distance (d)/time(t)

Solution:

Speed =?

Distance= 144km

Time = 3hrs

Speed = 144km/3hr

Speed= 48km/hr
