Speed is determined by dividing the distance travelled by the time taken to travel it. It gives the amount of time it took to travel a certain distance divided by the distance travelled.
Speed is inversely correlated with time and directly correlated with distance. As a result, distance equals speed times time, and time equals distance divided by speed; as speed rises, distance travelled will shorten, and vice versa.
Speed =distance/time
Given:
A lorry covers a distance of 100 km in 2 hours 30 minutes. A car runs with a speed of 55 km/hour
Find:
Determine the ratio of speeds
Solution:
Speed of lorry = 100/2.5
= 40 km/h
Ratio of lorry to car = 40:55
=8:11
Therefore the ratio of the speed of car and lorry = 8:11
