A lorry covers a distance of 100 km in 2 hours 30 minutes. A car runs with a speed of 55 km/hour. Determine the ratio of their speeds.​

A. 8:11
B. 20:11
C. 4:11
D. None of These

Concept:

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
