SPEED
Problem:
» What is the speed of a car that went a distance of 125 km in 2 h?
Solution:
» To calculate the speed, divide the given distance by the given time.
- [tex] \: { \underline{ \boxed{\bold{speed} = \frac{ \bold{distance}}{ \bold{time}}}}}[/tex] ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎
- [tex] \: { \underline{ \boxed{\bold{speed} = \frac{ \bold{125 \: km}}{ \bold{2 \: h}}}}}[/tex] ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎
- [tex] \: { \underline{ \boxed{\bold{speed} = { \bold{62.5\: km/h}}}}}[/tex] ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎
Therefore, the speed of the car ︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎ ︎︎ ︎ ︎︎ ︎ ︎ ︎ ︎ ︎is 62.5 km/h.
